David de Gea's situation at Manchester United is a big worry at the moment.
The Spanish goalkeeper only has eight months left on his current contract and time is fast running out for both parties to extend his stay.
It was believed that De Gea was open to signing an extension but Jose Mourinho admitted in his press conference earlier this week that he was 'not confident' that he would sign a new deal.
"I am not confident, but I'm also not worried," he told Sky Sports, per the Manchester Evening News. "I cannot find the word in English, but let's see what happens.
"Only the club, David and his people can answer that.
"My comment is only that everyone knows how good he is, how important he is for Manchester United and if the club want to be better than it is and not worse, obviously it would be very important to keep David."
De Gea has been at the club since 2011 but United may be forced to sign a replacement in the summer.
So with his future in doubt, a question has been raised by BT Sport: Is De Gea replaceable?
Paul Ince and Harry Redknapp both declared their belief that he could be replaced.
Ince said: "Yes, anyone's replaceable. [Peter] Schmeichel was. Anyone's replaceable."
And Harry Redknapp added: "Yes, he's replaceable. [He's a] Great 'keeper, but I'm sure there's other 'keepers around in the world.
While Steve Sidwell argued: "He's been the most consistent United player for the last seven years, he's won four Player of the Year's for them. He'll be very hard to replace."
So, what does Rio Ferdinand think?
The United legend saw the debate and he quickly made his feelings known on Twitter.
And it's fair to say he wants De Gea to stay.
He tweeted: "No... No.... & No Chance! Best Keeper in The World!"
Well, that's that then. There's no doubt that United will find it hard to replace the Spanish goalkeeper.
De Gea, meanwhile, has maintained that he is focused on winning games for United and not any other topics.
"What matters is the team and all of us being focused on what we need to focus on, which is winning games, rather than contracts or any topics that can be a distraction," he said, per Sky Sports. "What matters is focusing on football.
"We have an important game against Everton and we have some big fixtures over the coming months. I think that's what matters, rather than thinking about anything else."
