Darren Bent has urged Tottenham not to take a risk on playing Heung-min Son against Manchester United after his recent layoff. 

The former Spurs and England striker, speaking exclusively to Football Insider assistant editor Russell Edge, insists that clubs should always err on the side of caution when it comes to hamstring problems.

As quoted by Football.London, Jose Mourinho confessed that he did not know whether the South Korean star would be fit to feature against Manchester United on Sunday.

The winger went off at half-time against Newcastle United and missed both the League Cup win over Chelsea and the Europa League qualifying play-off versus Maccabi Haifa.

However, Bent insists that, having experienced hamstring problems of his own, there is no way Mourinho should risk Son on Sunday.

Bent told Football Insider: “Hamstrings are the one thing that you cannot rush back, I know for a fact because with hamstrings running in a straight line is never the issue.

“Obviously I’ve had a few hamstring injuries, that was never the issue because when the fitness instructor says: ‘Right, run from point A to point B in a straight line,’ you can do that and it’s not a problem, the hamstring will be fine.

“It’s when unseen circumstances happen, when you’re running in a straight line and the ball changes direction and you just change direction and change the angle of the hamstring, then bang, it goes.

“The best physios I worked with, even if they set a deadline for October 4th that Son will be fit for, you’ll be fit for October 4th but another week to 10 days, that’s when you’ll be available, just to make sure you’ve done everything you need to do. 

“As a player, it used to frustrate the life out of me because you said I was fit but you’re going to have days in that seven day period where it’s sore and just need that time to get over those niggles. 

“Even if Son is fit today, just to be on the safe side, you don’t want to play Son this weekend and lose him for another four weeks. You’d rather lose him for one and then have him for the next 10.”
