LIVE MANAGER WATCH: We keep track of Allardyce and Pardew as the bosses face their former clubs

Craig Hope: Allardyce and Pardew exchange a quick handshake before the Hammers boss disappears into the tunnel.

The victorious United manager takes to the field and applauds the travelling fans – his victory was deserved.

West Ham, however, have re-entered the relegation zone and pressure mounts on Allardyce.

Craig Hope: Game over as Cabaye curls home a delightful free-kick. Allardyce's response is a sorry slump into his dugout as he stares ponderously at the floor.

Craig Hope: Allardyce isn't too impressed with the news of five minutes added time; in fairness, one stoppage for a head injury was more than five minutes alone. He slams his chewing gum into the turf in protest.

That isn't going to change anything, however, and his side still trail with time running out.

Craig Hope: Interesting to note that neither manager has yet engaged in any dialogue with the fourth official and both have been on their best behaviour.

Pardew has just seen one blatant foul on Yoan Gouffran go unpunished but the Toon chief kept his counsel and his protest did not extend much beyond a disbelieving shrug of the shoulders.

Craig Hope: Ravel Morrison is now wearing one silver boot and one orange boot. The odd pair of each shoe have been left in the technical zone and Big Sam has just booted them clear having trodden on the discarded footwear.

Frustration is beginning to kick in and Allardyce had his head in his hands as Carroll blasted over from 10 yards soon after.

Craig Hope: Big Sam is heading every ball here as his side chase an equaliser. The manager nodded simultaneously with Carroll as he strained to get on the end of Downing's far-post delivery. The fans are back onside but still the hosts trail and time is running out for Allardyce.

Craig Hope: Can Big Andy be the saviour for Big Sam?

Yes, the Hammers boss has played his wild card and thrown Andy Carroll into battle against his former club.

There's a pat on the back before he enters the action and the home cheers drown out the howls of derision from the away end. Allardyce has his twin towers in attack with Carroll joining Carlton Cole up top.

Craig Hope: Big Sam looks like he's got a bit of belief back and he's returned to the touchline, where he watches in despair as Carlton Cole somehow stabs wide from just six yards out.

Allardyce has also sent Andy Carroll out to warm up and that seems to have rallied the home crowd who are now right behind their team.

The second period has started and we're nicely poised after that late response from the Hammers to pull it back to 2-1.

Craig Hope: Big Sam has decided to act and has introduced Ravel Morrison, the player who is said to want out of Upton Park. Needs must for the Hammers boss at present, however. This is a big half of football for the under-fire manager.

Craig Hope: A lifeline for Big Sam as Carlton Cole forces Mike Williamson to bundle into his own goal right on the cusp of half-time. Pardew slams his fist in frustration for it was a soft concession.

Allardyce, meanwhile, is perhaps a little embarrassed to celebrate too whole-heartedly and is embraced by assistant Neil McDonald.

Craig Hope: One restless local has to be restrained by stewards as he makes a charge on the home dugout. Allardyce doesn't flinch and keeps his eyes on the game; it's all getting a bit unpleasant for the Hammers boss.

Craig Hope: A fantastic team goal by Newcastle, finished by Loic Remy, does prompt a fist pump from Pardew as he spins on his heels and celebrates with assistants John Carver and Steve Stone.

Allardyce, meanwhile, remains staunchly on the touchline with jeers now emanating from the home crowd – they're not happy.

Craig Hope: Pardew is busy scribbling away on his notepad and, with his side leading and relatively comfortable, perhaps he's devising that community-service schedule, the punishment he imposed on himself following last weekend's foul-mouthed blast towards Manuel Pellegrini...

Craig Hope: Yohan Cabaye's quick feet and bottom-corner slot from 14 yards gives the visitors a 16th-minute lead.

Pardew's celebrations, however, are muted and he remains on the bench, eventually vacating his seat to issue instruction to his defence before the restart.

Allardyce was in his technical zone when Cabaye struck but very quickly retreated to the safety of his dugout and there he remains.

Craig Hope: We're on manager watch so we might as well tell you that Roy Hodgson is here at Upton Park this afternoon, Andy Carroll being the only obvious player on his radar. That's not unless Newcastle's Mike Williamson is set for a shock call-up...

Craig Hope: Allardyce, having just seen Loic Remy come within a whisker of giving the visitors the lead, has started to load the chewing gum. He does, though, afford himself a smile when Newcastle full-back Davide Santon tries his luck from all of 40 yards. Allardyce's grin tells you it was never threatening the target.

Craig Hope:  It's not long before Pardew comes in for a bit of stick from the home supporters. Rather than return a verbal volley, however, he retreats to his dugout – very sensible.

Craig Hope: Pardew has very quickly populated his technical zone, Allardyce preferring the front row of his dugout.

Craig Hope at Upton Park: Allardyce 1 Pardew 0 – Well, it may be a small victory but the West Ham boss made Pardew hover for their pre-game handshake, first signing autographs for the home fans behind his dugout. The pair duly embraced and Pardew returned to the away bench. We're underway.

A few scenes ahead of kick-off at Upton Park captured on camera

Pardew was in charge at West Ham between 2003 and 2006 and he seemed happy to be back at the Boleyn as the Newcastle coach pulled in, strolling through the tunnel to the pitch and even signing some autographs for early arrivals in the stands.

Welcome to our special 'Manager Watch' for this afternoon's West Ham v Newcastle United clash at Upton Park as both Sam Allardyce and Alan Pardew face their former employers.

Sportsmail's Craig Hope will be keeping an eagle-eye on every move the two make on the touchline during this important match.

The Hammers have won just once – at Cardiff City last weekend – in their last eight in the league and currently reside just one place above the drop zone.

There have been calls for Allardyce from the terraces and the Upton Park touchline can be a fairly lonely place when the locals are restless.

Opposite number Pardew is also feeling the strain and his side have lost four on the spin in all competitions.

During last weekend's 2-0 defeat to Manchester City he was criticised for an expletive-laden attack on Manuel Pellegrini, a verbal volley which saw the FA remind the Toon chief of his responsibilities this week.

Pardew has since revealed he will impose 'community service' on himself as punishment.
