Tottenham Hotspur manager Mauricio Pochettino has told Football.London that he felt his side lost their focus against West Ham United.

Spurs were in buoyant mood heading into tonight's Carabao Cup tie, as they hammered Liverpool 4-1 on Sunday afternoon just days after drawing 1-1 at Real Madrid.

It looked like Spurs were on course for another win, as Moussa Sissoko and Dele Alli struck to give Tottenham a 2-0 lead over West Ham in their Carabao Cup tie at Wembley Stadium.

However, West Ham rallied after the break, and quickly pulled themselves level as Andre Ayew found the net twice to give the Hammers hope of a stunning fightback.

Those hopes came true, as defender Angelo Ogbonna scored the winner to hand West Ham a passage into the last eight of the competition.

The win will give Slaven Bilic some much-needed breathing room after recent questions over his future, but counterpart Pochettino will not be impressed with how his side capitulated in the second half.

Pochettino decided to rotate his side after Sunday's win over Liverpool, and he told Football.London after the final whistle that it's not easy to play such a big game with a rotated side, accepting that it's his responsibility for losing momentum.

Pochettino added that he felt his side lacked aggression and focus in the second half, and allowed West Ham to get back into the game, showing his disappointment with his players.

“We showed a lack of aggression. Everything we were doing in the first half. You can never lose your focus,” said Pochettino. “We allowed them to come back into the game. In the first half it was under control. In the second half, we lost a bit of the aggression. They have players that are always dangerous.”

“Of course always it’s a consequence after such a game. We now need to find a solution to be competitive. I’m disappointed. In football sometimes you are in the sky after Real and Liverpool. I understand today it’s not easy to play this type of competition if you rotate. You can see last night and it’s difficult to keep the momentum. That’s my responsibility,” he added.
