Spurs boss Mauricio Pochettino made four changes to the team that started against Southampton, but it was the inclusion of midfielder Wanyama among the substitutes that was the biggest cause for cheer before kick-off away in Wales.
It was the first time the Kenyan captain was making it to the matchday squad since August after recovering from a knee injury. And Wanyama’s return was also sweet as the victory saw Tottenham climb to fifth above rivals Arsenal in the Premier League table.
With leading striker Harry Kane left on the bench, his deputy Fernando Llorente headed home against his former club from what appeared to be an offside position to put the dominant visitors ahead.
And after surviving spells of home pressure, Spurs launched an 89th-minute counter-attack and Kane found Dele Alli, who had his initial shot saved by Lukasz Fabianski before scoring with the rebound.
Wanyama was introduced in the 59th minute for Sanchez and was involved in the winning goal. The Kenyan captain now says he is happy to have kicked the ball again. “It's been a really tough four months, but my teammates have helped me. It feels good to be back and I'm happy to be playing again,” Wanyama told the club’s official website.
The result guaranteed Tottenham a third successive league win and inflicted a first defeat for Swansea under new manager Carlos Carvalhal as the Welsh club stayed at the foot of the table, four points adrift of safety.
