Jose Mourinho has suggested that luck is against Manchester United following a number of contentious refereeing decisions.

The Red Devils were denied what appeared to be a certain penalty in their goalless draw with Southampton last time out after Maya Yoshida handled the ball inside the box.

United boss Mourinho insists that other big calls have gone against his side in recent weeks, too, most notably in their defeat to Manchester City and more recently the 2-2 draw with Leicester City.

"I feel unlucky. But unlucky in football you have to change, which is what we try to do," he told reporters. "When I speak about three big decisions, penalties in matches where a penalty, and a possible goal, makes a huge difference, I want to say unlucky because it is what I feel.

"I could be here now with a bias theory, which I'm not going [to do] at all, because honestly I'm happy with the referees' performances in these matches, and [they] were just unlucky decisions."

United, without a win in their last four matches in all competitions, take on Everton at Goodison Park on Monday evening.
