Kevin Wimmer: Defender says his farewells at Cologne on Saturday

Tottenham have completed a deal to sign Cologne defender Kevin Wimmer and he will join the club in June, Sky sources understand.

The 22-year-old centre-half will sign a four-year contract and join the club for fee believed to be in the region of £4m.

Sky Sports reported in March that Spurs were discussing a potential deal for Wimmer, having wanted him to sign for the club in January but they could not offload either of their currently unwanted central-defenders Younes Kaboul and Vlad Chiriches, who were both made available for loan ahead of the winter window's deadline.

Kaboul and Chiriches are both set for the transfer list again this summer and Wimmer fits the club’s renewed policy of signing young, hungry players who are keen to develop under head coach Mauricio Pochettino and his staff.

Part of that policy is also to graduate more academy players into the first team and the first of those players will be Alex Pritchard, whom Sky Sports reported last Friday has begun discussions over a new four-year contract, having been assured over his future at White Hart Lane.

Pritchard has been in Spurs' academy since 2009 and spent the past season on loan at Brentford, where he was an established first-team member, scoring 12 goals, and won the clubs's Players' Player of Year award.

Sky sources also understand that Tottenham are not currently in negotiations to sign the FC Dnipro forward Yevhen Konoplyanka, despite reports.
