Roy Keane believes Paul Pogba could sign a new deal at Manchester United but doesn't believe the midfielder will help the club win Premier League titles.
The Frenchman is out of contract in 2022, leaving this summer as United 's last real opportunity to recoup any of the £89million they invested in 2016.
Pogba has praised Ole Gunnar Solskjaer's man-management this week after high-profile problems with Jose Mourinho, indicating he is happier at Old Trafford but doubts still remain over his future.
Keane believes that there's a good chance Pogba will renew terms but is yet to be convinced that the 28-year-old is 'world-class' and can lift United to a new level by winning major honours.
“I think he contributes to the team, not getting away with it but, if you’re talking about world-class, I think world-class players makes the players around them better. I don’t think he does that, I don’t think he does that at Manchester United," Keane told Sky Sports.
"When we look at crunch games, Leicester, quarter-final of the FA Cup, Man Utd at home to Man City in the League Cup. I look and when things aren’t going well, does he dig his team out of it, does he get them going, does he produce? To me, the answer is still no.
“He’s a talent and with a year left on his contract there’s a business side to it, they’ll want him tied up, they won’t want him leaving on a free next year. It’s an important summer coming up, if they get over the line with the Europa League and he’s happy with Ole, I think a deal could be done.
"He’s got an agent, he’ll have other options and there’s a shortage of talented players out there. But do I sit there and think ‘Pogba will get Manchester United back to league titles’, no, I don’t see that. I don’t think he makes other players better and that’s what brilliant players do and I’ve been fortunate enough to play with brilliant players.
"I think he’s a talented boy but do I think he’ll drive them along when they’re up against it? The evidence would suggest, in his few years at Man Utd, he hasn’t been able to do that. Results tell you that.”
