Thomas Tuchel said that Chelsea showed a "lack of concentration" as the German manager believes his side lost control of the game in the second half of Sunday's FA Cup win over Sheffield United.
The Blues were able to seal a 2-0 win on Sunday, with Oliver Norwood's first-half own goal and Hakim Ziyech's 92nd minute finish proving enough to seal a spot in the semi-final round.
Tuchel, however, wasn't pleased with the Blues' performance, as he was left disappointed by what turned out to be a disjointed second half.
