Jan Vertonghen is close to signing a new contract with Spurs but if they fail to make the Champions League again, his agent has warned Sky Sports he could leave.

The defender, who is currently happy and settled at White Hart Lane, has held ‘positive’ talks with the club, his agent said.

The 27-year-old signed for Spurs in 2012 from Ajax and has four years remaining on his current contract.

The Belgium international’s agent revealed in the summer that Vertonghen had attracted interest from several clubs, Barcelona included, but it appears likely he is going to put pen to paper at Spurs under new manager Mauricio Pochettino.

Vertonghen’s agent Mustapha Nakhli said: “We have spoken to Daniel Levy about a new contract for Jan and the negotiations were very good and we hope to sort everything out very soon.

“He is happy at Tottenham and wants to play for the club. He wants to play Champions League and has a very good feeling about the new manager.

“Last year they made many changes and brought in many new players and it was not so good, but this season it is possible for Tottenham to qualify for the Champions League.”

Vertonghen is expected to sign a long-term deal but Nakhli warned he may reassess things should Spurs miss out on the Champions League once again.

“Playing at the highest level is, of course, very important for Jan,” he said.

“If Tottenham do not qualify for the Champions League this year, then we will have to see what happens next summer.”

Spurs have failed to make it to the Champions League since the 2010/11 season, when Harry Redknapp guided the club to the quarter-finals.
