1:56 Jose Mourinho reveals Paul Pogba has been the hardest worker in training and will play against West Ham Jose Mourinho reveals Paul Pogba has been the hardest worker in training and will play against West Ham

Jose Mourinho says Paul Pogba was never officially Manchester United's vice-captain.

Mourinho announced earlier in the week that Pogba was not his "second captain anymore" - after the midfielder criticised United's tactics during last week's 1-1 draw with Wolves.

The United manager clarified the situation further on Friday, saying Pogba would play at West Ham on Saturday but was "just a player and not a captain".

"Paul was not the vice-captain," Mourinho said.

"We had Valencia as the captain and then we had a group of players that could be the vice captain - one day I gave it to David de Gea, I gave it to Ashley Young, to Chris Smalling.

Antonio Valencia is first choice for the captaincy at Manchester United

"I first thought about Paul last season, because (he is) a player of a different generation, younger player, the captain of the future.

"Because Valencia, Young, they are more or less the same age, the same generation. But he (Pogba) was not the vice-captain, so now we don't have the vice-captain.

"Now it depends on the match, and depends on if Valencia is playing or not.

"If Valencia is playing, Valencia is the captain. If he is not playing, I will try and go in another direction."

Mourinho is adamant that the week's events have not had a negative impact on his squad ahead of Saturday's game at the London Stadium.

"I expect to win tomorrow," he added. "I expect to play very well tomorrow - we have worked very well, especially Wednesday and Thursday, so tomorrow I expect a very good performance and I expect to win a very difficult match.

"I don't come here and say 'the training session was not good and I have a bad feeling and I have a feeling that tomorrow we are not going to play well and we are not going to win'.

"I think tomorrow we are going to play very well, and I think we are going to win against a very good opponent, an opponent with great investment, with a champion manager (Manuel Pellegrini), and lots of talented players.

"Very difficult but I am very positive."
