Kane has scored seven goals in 10 games under Mourinho but struggled to make an impact against United — his first match since returning from a hamstring surgery in January — and Mourinho said Merson was wrong to judge him based on one game.

“The record of goals that Harry has with me (in charge) is easy for you to see … I can say I had a few strikers who played for me and they are not bad,” Mourinho told reporters in a virtual news conference on Monday.

In a five-minute-long response, Mourinho then went on to mention the likes of Didier Drogba, Cristiano Ronaldo, Karim Benzema, Diego Milito and Zlatan Ibrahimovic, reeling off their goal scoring statistics under his tenures at various clubs.

“So dear Paul, I have lots of respect for you,” Mourinho added. “I think Harry Kane has no problems at all to score goals in my teams, especially when he’s fit, when he’s fresh and he has routines of playing.”

Mourinho confirmed forward Lucas Moura was available for Tuesday’s London derby at home to West Ham United after recovering from an injury while Dele Alli is also in contention after serving his one-match suspension.

“For the first time since I arrived, all six attacking players are available for the game,” Mourinho said.

“I’ve had matches with only one and now finally I have six so I can have people playing and on the bench to rotate players. Our attacking options for this match are really good.”

Spurs are eighth in the standings on 42 points from 30 games and chasing a European spot, while 17th-placed West Ham have 27 points, the same as third-bottom Bournemouth and only outside the relegation zone due to a superior goal difference.
