Chelsea head coach Thomas Tuchel has suggested that he had been left frustrated by Chelsea's performance during the 1-0 win at Tottenham Hotspur in the EFL Cup semi-finals.
Leading 2-0 from the first leg, the Blues dominated the opening stages in North London and were rewarded when Antonio Rudiger headed in the only goal of the contest.
However, Spurs were provided with openings during the closing 50 minutes, the home side having two goals correctly chalked off by VAR and a later effort from Harry Kane ruled out for offside.
Kepa Arrizabalaga was also forced into several saves during the second half, and Tuchel was not as pleased as he may have been after the full-time whistle.
Speaking to BBC Radio 5 live, Tuchel said: "We're happy with the result. In the first half we were the better team and we deserved to be up.
"But we lost concentration and lost focus in the last 15 minutes of the first half and again in the second half. We were almost punished for lack of focus.
"We played at 90% and that's not our style - we shouldn't do this. We had to work hard and it was not our best performance - we were better in the first leg."
Chelsea will play either Arsenal or Liverpool in the final, which is due to take place on February 27.
