Herrera vows to keep proving his worth to Man Utd's Mourinho

Mourinho's Manchester United side stunned the league leaders with a 2-0 victory at the weekend, which helped the Red Devils exact revenge for the two previous wins Chelsea managed to secure over the club this season. When United were without the ball, he was assigned to man-mark Eden Hazard - completely nullifying the threat from the Belgian for the entire match.

The former England global has started only 13 games for United this season and was linked with a move to the Chinese Super League in January and February.

"We have great players and Manchester United has the capacity to sign big players, so I can not sleep", Herrera told United's official website.

He said: "Nobody will remember this part of the season if I don't perform well at the end". I just look forward.

"I am a team player, I want to give everything for the manager and I don't look back".

"They had everything to play for in that they are striving for that Champions League place, which I have always felt they will get, and have a manager who is quite good technically and tactically", he added. I am happy, but I am not finished yet.

"For now, I'm feeling very well here in Monaco", he told CNN.

"I will always be thankful, but football changes", he said. Also, when everyone is telling you you're having a great season, you're having a very good game, you're playing very well, I don't think it is good for yourself so I don't listen too much.

The France global has completed 90 minutes just three times in the Premier League this season, and Mourinho has now warned Martial that he must adapt if he is to thrive. But today he scored and it was at the beginning of the match, which gave the team more confidence and stability. I don't think a lot of people saw that scoreline coming or the type of game to be honest.

"It's my third season in France, but of course all the players want to play in the best leagues".
