Tottenham Hotspur boss Jose Mourinho is not too concerned about Jan Vertonghen leaving the club.

That is the view of pundit Alan Smith.

He believes that Vertonghen will move on as his contract expires, and Mourinho is happy to let the veteran depart.

Spurs are likely to sign a replacement defender in the summer transfer window.

"Vertonghen is 33 years of age and his best form is behind him," Smith told Sky Sports.

"We saw that in the latter stages of this season so Jose Mourinho won't be overly fussed if he's not available and if his mind is elsewhere."

He added: "We've got to think that most of these players who are out of contract, certainly the most attractive ones to other clubs, they'll have half an idea at least over where they're going to go and who's interested.

"You could understand if they don't want to jeopardise that move. Vertonghen's situation is obviously different to a 22-year-old who hasn't yet had a career or made his money.

"Vertonghen just wants to elongate his career, maybe in another country - he's spoken about learning another language. Only the individual can answer, but I suspect he won't want to ruin a potential move coming up by playing in a few games.

"He's got one of the best attitudes around - we've seen that over a number of years in England - but at this stage, you're thinking about yourself and your family if you get injured."
