Manchester, March 14: Manchester United coach Jose Mourinho lashed out at referee Michael Oliver, claiming the 32-year-old official has cost his team four times this season following the red card shown to Ander Herrera during the FA Cup quarter-final.
"Everybody can analyse in different perspectives, everyone can do it in a different way, but I think we all watched the match until the red card," Mourinho told www.manutd.com.
"After the red card, then we can compare the decisions of these two yellow cards, in this case the second yellow card with ones that were not given.
"But I don't want to go in that direction. This season Mr Michael Oliver is a referee with fantastic potential, but with Manchester United we were a bit unlucky.
"In four matches, (we have had) three penalties and one red card in such an early moment of the game.
"But again I cannot change that, but I can try to interfere in the Thursday match (against Rostov) which is the match that is coming and now we have to rest."
Herrera was shown the second yellow in the first half for two fouls on Eden Hazard.
