Fernando Llorente scored his first Premier League goal for Tottenham Hotspur to help inflict a 2-0 defeat on his former club Swansea City on Tuesday.
Harry Kane was rested on a stormy night at the Liberty Stadium, but his replacement stepped up before Dele Alli sealed the three points late on for Spurs.
Tottenham remain on the winning trail ahead of two more games in the next five days, but Swansea will complain that they did not get the benefit of the decisions.
It took Llorente only 12 minutes to regain his goalscoring touch on his old stomping ground, as he headed home a Christian Eriksen set piece at the near post.
However, the assistant referee failed to spot that the Spaniard, who scored 15 goals for Swansea last season, had drifted several yards offside in getting goalside of Federico Fernandez.
Tottenham completely dominated for the opening half an hour, but a combination of a deep Swansea backline and the wet and blustery conditions made it difficult for them to create chances.
Their only other opportunity of the first half came when Dele Alli dragged a half-volley wide from Llorente’s layoff on 23 minutes.
Although Swansea were slightly more progressive after the break, they still did not possess much of a goalscoring threat, and yet were denied a route back into the game when Davinson Sanchez survived what appeared to be a blatant second yellow card.
Swansea twice came close to an equaliser in the 70th minute, when Ayew rounded Lloris only to see his shot blocked, and Mike van der Hoorn headed against the frame of the goal from Tom Carroll’s corner.
Once Spurs emerged through that spell unscathed, they had seen off the Swansea threat and nearly wrapped up the game when Son Heung-min side-footed inches wide from Kieran Trippier’s deep cross.
Kane came off the bench to supply Tottenham’s second with an inch-perfect assist for Alli, who saw his initial effort saved by Fabianski but adjusted his feet quickly to convert the rebound on 89 minutes.
The result sees Tottenham climb above rivals Arsenal into fifth in the table, while Swansea remain bottom after a first defeat under new manager Carlos Carvalhal.
