The Blues boss feels the club must make the right moves to make up for "lost ground" before the transfer period is over
Frank Lampard says Chelsea need to sign new players in the January transfer window after they survived a late scare to beat Hull 2-1 in the FA Cup fourth round.
Despite Michy Batshuayi's early opener and Fikayo Tomori's second-half strike, the Blues had to endure a nervy end to the game after Kamil Grosicki pulled one back for the hosts with 12 minutes left.
Chelsea boss Lampard has expressed his frustration with his side's inability to put results beyond doubt as they look to keep their cup run going, stay in the Premier League's top four and compete in the Champions League.
