​Manchester United manager Jose Mourinho was not impressed by his players over-celebrating Juan Mata's opening goal against Hull City, claiming there was no reason to celebrate the goal.

United who beat Hull City 2-0 in the first leg of the semi-final of the EFL Cup at Old Trafford on Wednesday, took until 56 minutes to open the visitors defense, with their first goal coming from Mata.

The Spaniard turned Henrikh Mkhitaryan's header beyond Hull keeper Eldin Jakupovic leading to lengthy celebrations among the United players, something which annoyed Mourinho.

"We needed to play. In cup ties every goal can be crucial so why celebrate when you have half an hour to play? I don't think we should, there is no reason to celebrate the first goal", he said to ​Sky Sports.

These comments by the Portugese come in the wake of a request to United supporters to raise their game, when Liverpool come visiting on Sunday. The 53-year-old asking supporters not to 'just come to the theatre', but to 'play with us'.

The Red Devils go into the second leg with a two goal lead, thanks to strikes from Mata and Belgian Marouane Fellaini. The return game is scheduled to take place on the 26th of January at the KCOM Stadium.
