Vincent Janssen, Erik Lamela and Moussa Sissoko remain a “dilemma” for Tottenham manager Mauricio Pochettino, according to a report.

ESPN FC claim the Spurs senior trio have failed to prove consistently effective for the team this season.

Tottenham are third in the Premier League ahead of Saturday’s trip to Bournemouth and remain in the running to qualify for the knockout stages of the Champions League.

But the report states the jury is out on summer signings Janssen and Sissoko, who cost a combined £48million, and 2013 arrival Lamela, whose fee was £26million.

“For Pochettino, three players remain a dilemma: Janssen, Lamela and Mousa Sissoko,” the ESPN FC report states. “The manager has remained extremely loyal to Janssen — the Dutchman did have his best 45 minutes for the club in the first half agains Leverkusen — but his solitary goal, a penalty against Gillingham, tells its own story.

“Spurs can’t indefinitely afford the luxury of a striker who doesn’t score. Lamela also appears to have gone backwards this season.

“Having shown signs of adjusting to the Premier League last year, he has reverted to being too ineffectual. As for Sissoko, it appears the manager has no idea where he wants to play him or, indeed, why he bought him.”

Tottenham could end the weekend at the Premier League summit if the results go their way after taking 18 points from their first eight matches.

Pochettino’s side are the only unbeaten team in the English top flight, although they are behind leaders Manchester City and London rivals Arsenal ,who are both on 19 points.
