Tottenham fans have expressed their surprise on Twitter as manager Mauricio Pochettino enters talks to sign Crystal Palace attacker Wilfried Zaha.

Sky Sports claimed on their transfer centre blog on Thursday (1.19pm) that the north London side are in negotiations with their London rivals over a deal for the winger.

A fee for the England international is being discussed of around £15million, which is the same fee Manchester United paid Crystal Palace back in 2013.

The likelihood is growing that Zaha could become Spurs’ fifth summer signing, as the club are also in advanced talks to sign goalkeeper Pau Lopez and winger Georges-Kevin N’Koudou.

Tottenham fans are shocked at the move, with many believing the deal could be desperate one with six days remaining in the transfer window.

Here are a selection of their messages on Twitter:

The Londoners have signed midfielder Victor Wanyama and striker Vincent Jansson so far this summer.

Spanish newspaper Sport claim Lopez will undergo a Spurs medical on Saturday and Sky Sports revealed on their Twitter account last weekend that Tottenham have also agreed a deal with Marseille for winger Georges-Kevin N’Koudou, although that has not been officially announced.

Zaha, 23,  impressed for Alan Pardew’s side last season, scoring five goals and producing seven assists in 43 league and cup encounters.

Zaha has played the full 90 minutes in each of Palace’s opening two matches of the Premier League season, including last Saturday’s 1-0 defeat against Spurs at White Hart Lane.
