So it was not a surprise when Arsenal took the lead after quarter of an hour. Kane fell as he was attempting a turn on the edge of the Arsenal area and as the Arsenal supporters yelled their glee, the ball was cleared to the half way line. Davinson Sanchez botched his interception and headed the ball straight to Lacazette. Spurs were suddenly exposed.
Lacazette played a simple pass forward and now Ramsey was free, running alone at Lloris from the edge of the centre circle. Ramsey, who is leaving for Juventus in the summer and was playing in his final north London derby, stayed calm, took the ball around the Spurs keeper, staved off a late, desperate challenge and slid the ball into the net.
Spurs struggled to find any of the fluency that characterised their game earlier in the season and did not muster a shot on goal until after half an hour had elapsed. Kane, who returned from injury last week, still did not look match sharp. He did score a superb header from a Christian Eriksen free kick but he was offside.
