Tottenham boss Jose Mourinho is not concerned about his defence, despite their late capitulation against West Ham.

Spurs were coasting to three points after a devastating opening spell saw them go 3-0 up inside 16 minutes thanks to Son Heung-min’s 45-second opener and Harry Kane’s brace.

But Manuel Lanzini’s stunning stoppage-time strike for West Ham completed a comeback started by Fabian Balbuena and a Davinson Sanchez own goal which left Mourinho’s men shattered.

The Portuguese, who had been determined to shore things up at the back this season, is convinced their late crumble was a blip and pointed to the types of goals they have conceded.

“We have new players,” he said. “We played much better than last season. I can say the same about West Ham.

“West Ham is a much better team than it was when (David) Moyes arrived. The team is in evolution, we play much better, we know how we want to play.

“Defensively the team is much better than before. Can I say that in all this Premier League that we’re playing, five matches, we concede penalties or free-kicks and only one goal from open play – Danny Ings (against Southampton).

“And this shot was also from the sequence of a free-kick. I can look at that and say, yes a team that plays so well for periods and does the most difficult thing in football – scores goals and we’re scoring a lot of goals – cannot lose two points like we did.”

Mourinho would not lay the blame for the draw with Gareth Bale who made his second debut for Spurs, joining the game from the bench in the 65th minute.

There has been plenty of hype surrounding Bale’s return, which was almost marked with a dream goal that would have made it 4-2, but Mourinho did not think Bale’s arrival affected the game in a negative manner.

“Don’t think so, honestly don’t think so,” he said.

“The decision not to start him was I think a good decision. It was a message to the team that in this team everybody has to fight for positions.

“He’s very well accepted in the group. Everyone likes him, and I believe he also likes what he found here. So everything is positive and the focus was not on him.

“It’s a pity that he couldn’t score that fourth goal. But that’s football.”
