West Ham United appointed Manuel Pellegrini as their new manager last Wednesday, and the former Manchester City boss will have already started getting to work on assessing the current squad that he has at his disposal.

The 64-year-old will certainly be keen to give everyone a chance to impress before he makes too many moves in the transfer window, and there may well be some individuals that have a big point to prove following a disappointing campaign where the east London outfit flirted with relegation.

The Chilean boss, who could look to be reunited with three players he has worked with previously this summer, showed during his final season with City in 2015/16 that he isn't afraid to make big team selection decisions having kept the likes of Vincent Kompany and Yaya Toure on the substitutes' bench in huge matches, and he will want to be a disciplinarian again to ensure that he doesn't lose his record of never finishing outside of the top seven while being a manager in European football.

There are certain stars that may not be able to keep up with the 64-year-old's demands based on previous instances, and those could be the ones that are shipped out of the London Stadium exit door first.

Here are four West Ham players who won't last long under Pellegrini's tutelage…

With Joe Hart returning to Manchester City following a disappointing loan spell at the London Stadium it seems almost certain that Pellegrini will look to bring a new goalkeeper in this summer, and he has been linked with a player he worked with at the Etihad in Willy Caballero.

While the stopper is 36, the Chilean manager would likely make him the number one if he did sign him given he is currently back-up at Chelsea, and that may not go down well with Adrian who has reacted badly to being dropped in the past.

Losing his place to Caballero would surely anger the Spaniard, and his 64-year-old manager may choose to wield the axe if that proves to be the case.

While Kompany was City captain and one of their most influential players, Pellegrini showed how ruthless he can be by leaving the Belgian out of the starting XI for a huge Champions League clash with Paris Saint-Germain even when he was fit again after suffering from injury.

Like Kompany, Reid is an influential member of the West Ham backline but injuries have hampered him over the course of the past few seasons, and the 29-year-old only made 18 Premier League appearances last term as he suffered from calf, groin and knee problems.

Pellegrini likely won't be willing to put up with the New Zealand international – whose form has clearly dipped – if those issues continue, and if he brings in a new centre-back this summer to join Declan Rice and Angelo Ogbonna in defence, Reid could find himself surplus to requirements.

Pellegrini will demand high work-rate and impeccable tactical awareness from his players next season if they are to push for a top-seven finish, and it is difficult to see Kouyate fitting in under Chilean on that basis.

While the Senegal international did improve towards the end of the campaign following some poor performances previously, he looked at times as though he didn't know what role he was supposed to be playing.

Whether that was the fault of Slaven Bilic and David Moyes remains to be seen, but if he shows the same lack of quality during pre-season Pellegrini surely won't put up with him for too long – especially if he has Mark Noble, Pedro Obiang and a potential new midfielder in the squad.

Like Reid, Carroll is another that has suffered from injury problems during the last couple of seasons – and since he joined the club in general – and while his first-team chances should be boosted if Pellegrini plays two up top, it may not be that easy.

Javier Hernandez is likely to be a regular starter following a difficult debut campaign at the London Stadium, while Marko Arnautovic may keep his spot as a centre-forward having been the first-choice in that position for the majority of the 2017/18 season.

Carroll threw his toys out of the pram when he failed to come on as a substitute in the defeat against Manchester City last month, and if he were to pull a similar stunt again the Chilean would not take to it kindly.
