Tottenham have not increased their £12million offer for Crystal Palace winger Wilfried Zaha to £18million, according to a reliable journalist.

Sports website HITC previously claimed that the south east London club had rejected an improved second bid from Mauricio Pochettino’s side, after an initial £12million offer was made.

Palace chairman Steve Parish dismissed Spurs’ original £12million opening gambit for Zaha as “ridiculous” last Thursday.

Respected Mirror journalist Darren Lewis revealed on his personal Twitter account that Spurs have not upped their offer but Pochettino is still keen on pushing through a late deal for Zaha.

It is believed that Tottenham will have to get closer to the £25million fee Crystal Palace received from Everton for former winger Yannick Bolasie to seal a deal.

Palace are considering a few possible replacements for Zaha, but with the deadline closing in on Wednesday they are doubtful Spurs will match their valuation.

However, it is also claimed that the 23-year-old is not happy with his current terms at Sellhurst Park and that talks over a new deal have not accelerated, despite him having four years left on his current deal.

This has alerted Tottenham to the England international, with the north London side knowing they can offer him the sort of wage packet that the former Manchester United winger wants.

Football Insider revealed on Saturday that Spurs had offered Zaha a double-your-money contract to push through a deal for the winger by Wednesday’s transfer cut-off.

The two-time England international impressed for Alan Pardew’s side last season, scoring five goals and producing seven assists in 43 league and cup encounters.

Tottenham have been in the market for a new winger, with Marseille’s Georges N’Koudou edging closer to a move before Wednesday’s deadline.
