Paul Merson believes that Tottenham manager Mauricio Pochettino could leave the club if the squad is not improved.

Spurs signed Victor Wanyama, Vincent Janssen, Moussa Sissoko and Georges-Kevin N’Koudou in the summer transfer window, but they have failed to strengthen the team.

Wanyama, 25, is the only summer recruit to force his way into the regular starting XI and Spurs have won just once in their last nine games across all competitions.

Janssen failed to capitalise on Harry Kane’s 10-game absence through injury and is still without a goal from open play, while Sissoko and N’Koudou are yet to find any consistency.

Merson claims that Argentinian manager Pochettino will leave Spurs if he is not allowed to sign some bigger names and thinks that several clubs would be interested in his services.

“I think Pochettino can see they are a way off and knows he needs a few more players,” Merson wrote in the Daily Star. “If he doesn’t get them I think he’ll be gone.

“He’s an ambitious manager. Bigger clubs wanted him in the summer and he’ll not be short of offers if he walks.”

Pochettino moved to White Hart Lane in 2014 and has become extremely popular with the Spurs supporters.

The 44-year-old manager led the north London club to fifth in the Premier League during his first season and finished third-placed last campaign as they challenged for the title.

He began his managerial career in 2009 with Espanyol in Spain and also took charge of 60 games with Southampton.

Pochettino is well recognised for his aggressive high pressing style and that proved crucial in the club’s success last season.

Spurs are still the only unbeaten side in the Premier League this season, but the club have already been eliminated from the Champions League and are becoming very reliant on striker Kane.

In other Tottenham news, these three players will be crucial in Saturday’s game against Chelsea.
