Vincent Janssen needs to do more to prove himself at Tottenham, says Mauricio Pochettino

Mauricio Pochettino has urged Vincent Janssen to prove himself at Tottenham

Tottenham boss Mauricio Pochettino says Vincent Janssen needs to "show more" if he is to work his way back into the fold at White Hart Lane.

Janssen is yet to score from open play since joining Spurs in a £17.5m deal from AZ Alkmaar last summer.

The 22-year-old Netherlands international has started just one game in the last three months and was left out of Tottenham's match day squad for the Europa League defeat to Gent on Thursday night.

Pochettino is expected to make a number of changes to his first team for Sunday's trip to Fulham in the FA Cup.

However, the former Southampton boss could not confirm if Janssen would even make the bench for the game at Craven Cottage.

"Maybe, maybe," Pochettino said. "Against Gent he was out of the squad. He needs to show more and we'll see.

"Maybe he will have the opportunity to be on the bench or play [from the start]. We cannot be sure if he will be in the squad, on the bench or start from the beginning.

"Performance is always about how the players show their quality, their belief on the training ground.

"When you select the starting XI and the bench, I try to be fair. It's normal that maybe he needs to show more."

Tottenham have won only two of their last six matches in all competitions and have now dropped to third in the Premier League following their defeat to Liverpool last weekend.

Pochettino admits he is upset with Tottenham's recent dip in form but expects his side to return to winning ways at Fulham.

"It's about trying to give support to help them recover the same spirit and the same feeling that was before Liverpool," he said.

"I am not unhappy, I'm not upset. Sometimes things happen, up and down. Now we try to be all together and try to find all together the way to change this run."

Kieran Trippier, Harry Winks, Michel Vorm, Joshua Onomah and Cameron Carter-Vickers could all be given a chance to impress against Fulham, with a number of first-team regulars set to be rested for the return fixture against Gent on Thursday.

"You know how tough the competition is in England - the Premier League, the Champions League, the Europa League," Pochettino said.

"Always it's too difficult, because maybe some problems will appear with the players [like] they are not fresh and it's a big risk to play them on Sunday.

"After we have a lot of games ahead to play. It's not a lack of respect [for the FA Cup]. We try to give all the players an opportunity."
