Manchester United news: 'Obvious' that Red Devils needs a new striker, says Ralf Rangnick

There is a good chance that the club will have a new manager in the summer too, and Rangnick believes finding a new man to spearhead their side will be the top priority for whoever comes in.

"Edinson's contract is running out in the summer and the club needs the best possible centre forward," Rangnick said.

"This is an obvious one. I think everybody's aware of that."

Man Utd have had some gripes with officials of late, with controversial decisions going against them in the 1-1 draw with Burnley and the FA Cup defeat to Middlesbrough.

Rangnick, though, says they can't afford to bemoan such things.

"I wouldn't even know who to speak to," Rangnick said when asked if he would be making a complaint. "I don't think it would change anything.

"Of course, we were extremely unlucky with those decisions, both with the handball against Middlesbrough and the two disallowed goals at Burnley.

"But, again, this is also football, we have to learn and deal with it.

"Of course we would've wished those decisions to be different but - in the end - they were as they were and even if I call somebody now, this will not change anything with regard to the results.

"We have to put our full focus on those things that we can influence and what we can influence is the development that has already taken place and make sure that this will happen again in the next couple of weeks.

"That we improve our performances, that we create as many chances as we possibly can and only allow a minimum of opportunities to the other team. This is in football, is what it's all about.

"It sounds pretty simple but that's what it's about: to create as many chances as we possibly can and allow the other team as few as possible, only maybe one or two per game.

"Under normal circumstances, then you also win the games."
