The big Kenyan midfielder was heavily linked with a move to Tottenham Hotspur last summer.

That decision came after a lengthy saga which saw Tottenham repeatedly linked, but the Saints were thought to be upset with the North Londoners over their hijacking of Toby Alderweireld and refused to sell the Kenyan to Spurs.
But with another transfer window on the horizon, manager Ronald Koeman is braced for interest in the big midfielder, with a report from The Mail last month indicating that Tottenham will go back in for him.
That being said, fresh reports state that although Koeman is worried about losing Wanyama, Sky Sports suggests that relations between both clubs remain 'difficult', which may plunge Mauricio Pochettino's hopes of signing him into doubt.
There is, of course, also the Pochettino factor, with the Argentine quitting Southampton to join Tottenham in 2014.
Saying that, do Spurs need him? In Eric Dier, Pochettino has one of the best defensive midfielders in the business, the Englishman being exceptional this past season. Competition of Wanyama's calibre would improve him, sure, but Tottenham have more pressing positions to strengthen before that, perhaps.
