Newcastle United legend Alan Shearer says Manchester United's FA Cup final triumph can't mask their problems.

Shearer wrote for BBC Sport: "Whoever Manchester United's manager is next season, their team needs major surgery if they want to challenge and get to where they want to be, or believe they should be.

"It has been clear for a while that this is not a great United side.

"And, if Saturday's FA Cup final win over Crystal Palace was Louis van Gaal's last game in charge, then he has gone out with what will be remembered as a typical performance of his time as boss.

"The same thing has happened many times before this season - they were the better team so they did deserve to beat Palace, but they did not play particularly well.

"United had to win the FA Cup on Saturday to take any credibility away from this season.

"But the fact they have got some silverware does not change the fact it has been a hugely disappointing campaign for them."
