Spurs count cost of Bostock deal

Tottenham could eventually pay more than US$4million to Crystal Palace for promising midfielder John Bostock.

Palace chairman Simon Jordan was angered by a Football League tribunal ordering Spurs to give a US$1.4million downpayment on the 16-year-old but there are other clauses that could see the total rise.

The Barclays Premier League club will pay an extra US$2.9million if Bostock makes 40 appearances for his new club and a full international debut.

Palace will also get a 15% cut of any future deal to take the youngster away from White Hart Lane, with the fresh details emerging from a letter to a Palace supporters' group from the league.

Bostock has been earmarked for the future but could make appearances next season following changes in the rules to allow seven substitutes.

Luka Modric and Giovani dos Santos have also arrived at Spurs this summer but strikers Dimitar Berbatov and Robbie Keane want to leave, for Manchester United and Liverpool respectively.

It means head coach Juande Ramos will be required to bring in another striker if they depart, and Zenit St Petersburg have claimed Spurs are interested in Andrei Arshavin but need to raise their valuation of him over the US$40million mark.

They have also been linked with his Russia team-mate Roman Pavlyuchenko, and are in the hunt for Blackburn winger David Bentley.

Steed Malbranque, Teemu Tainio, Pascal Chimbonda and Younes Kaboul are among the players Ramos has allowed to leave, with Sunderland bidding for the quartet.

Tainio and Chimbonda have been responsive to the proposal of playing under Roy Keane, while Portsmouth and Aston Villa are both thought to also be interested in Kaboul.
