There has been much speculation that Manchester United manager David Moyes will overhaul his squad with a summer clearout at the end of the season.
Some pundits, such as former player Stan Collymore, have even suggested that Moyes should sell everyone apart from a handful of players who deserve to stay.
But which five players must Moyes keep?
There aren't many Premier League right-backs better than Rafael, who makes Manchester United look so much better - in both a defensive and attacking sense - when he's on the pitch.
The 23-year-old has been with the Red Devils' since 2008, as has his twin brother, Fabio.
However, the twins might be separated this summer...
Even though his long-term position is still up in the air, it's abundantly clear that Phil Jones will become a first-class centre-back or holding midfielder.
The versatile 21-year-old might not go on to become the greatest player in Manchester United's history, like Sir Alex Ferguson once suggested, but he is already an integral part of the current team.
David de Gea
David de Gea was named in the Premier League Team of the Year last season - and right now, it's fair to say that the Spaniard is the best goalkeeper in England's top-flight domestic league.
Ar 23, the best is yet to come from De Gea. But how long until Manchester United are fending off the likes of Real Madrid and Barcelona for his signature?
Belgium-born winger Adnan Januzaj signed a long-term contract earlier this season, which was tremendous news for every Manchester United supporter.
The 18-year-old has been one of the Red Devils' best players this season - and has such a bright future ahead of him.
Even if United receive a few tempting offers in the summer, the reigning Premier League champions must do all they can to make sure he remains a Manchester United player - including handing him the coveted No. 7 shirt.
Wayne Rooney is the heartbeat of Manchester United - and has been for the best part of seven or eight years now.
The England international will only have 12 months remaining on his contract in the summer, and it's imperative that David Moyes and co. persuade him to extent his deal.
Without Rooney, next season could be even bleaker for the Red Devils.
