Rio Ferdinand has revealed that he has been left unimpressed by Tottenham’s summer signings.

The north London club added four senior players to their side in the window with Victor Wanyama, Vincent Janssen, Georges-Kevin N’Koudou and Moussa Sissoko all moving to White Hart Lane.

The quartet cost the club £67.4million in transfer fees and former Manchester United defender Ferdinand has stated that he believes Wanyama is the only one to have made an impact in the side.

“Tottenham are not winning enough games this season and one of the reasons why is the signings they made in the summer,” Ferdinand wrote in the Evening Standard.

“The club spent £68million on Victor Wanyama, Moussa Sissoko, Vincent Janssen and Georges-Kevin N’Koudou. It is still early in their careers at Spurs and they obviously have talent. But if I was at a rival club, none of those buys would have scared me.

“When I was at Manchester United, the players always responded far better and raised their game when a big player came in. The kind of signing that makes everyone sit up and go ‘woah’.

“We had a team that was used to winning for many years and it was a case of adding a few diamonds to it.”

He added: “Tottenham are obviously not in the same situation as Manchester United were back then. They still need to find a way to win trophies, as well as working out a way of adding players to improve the team.

“But of the four they bought, only Wanyama has made a real impact on the side. He has started very well, yet the others haven’t really added to the team in terms of goals or performances. I’m sure that is a frustration for Mauricio Pochettino at the moment.

“Tottenham are drawing too many games and I believe they have just become a bit too predictable.”

Tottenham are currently on a poor run of five matches without a victory in all competitions.

They were knocked out of the EFL Cup last week by Liverpool and currently sit in fifth place in the Premier League despite remaining the only unbeaten side after 10 fixtures.

Spurs are three points from league leaders Manchester City and they face a big week ahead with a clash at Wembley against Bayer Leverkusen in the Champions League on Wednesday before travelling to the Emirates to face fierce rivals Arsenal on Sunday.
