Tottenham Hotspur are ready to let Icelandic midfielder Gylfi Sigurdsson leave the club this summer, [football] direct news understands.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });The 24-year-old attacker has not managed to find his best form at White Hart Lane since signing for the club from Hoffenheim last season, and no longer seems to be in Tim Sherwood’s plans. Sigurdsson had initially caught Tottenham’s eye with some fine performances in a loan spell with Swansea City, but a return to the Bundesliga now seems possible with a number of clubs believed to be interested in signing him ahead of next season. It looks increasingly like Spurs will not stand in the way of Sigurdsson leaving, as they plan a revamp of their squad in the next transfer window. Spurs’ form has improved recently, but some performances this season have caused concern, particularly after the club spent heavily on new players last summer in a bid to replace Gareth Bale. Several other players could be set for the axe as well, with the likes of Roberto Soldado and Erik Lamela tipped to make quick exits after only joining this season.
