Conor Gallagher admitted Chelsea's misfiring squad are angry after their limp 1-0 defeat at Wolves.
Matheus Nunes' first-half stunner sunk the Blues as Frank Lampard failed to inspire his side in his first game back as manager.
Lampard returned after last week's sacking of Graham Potter and Chelsea remain 11th in the Premier League - ahead of Wednesday's Champions League quarter final first leg at Real Madrid.
'We can't have too many complaints,' midfielder Gallagher told the club's official site.
'It was a disappointing game. We had confidence, we were up for it and excited for the game but we're disappointed and angry because we want it so bad.
