Chelsea's interim boss Frank Lampard and former star Joe Cole believe a "lack of belief" among the players is one of the biggest problems affecting the Blues at the moment.
Chelsea are currently 11th in the Premier League table and are facing an uphill battle if they are to qualify for the semi-finals of this year's Champions League, having lost 2-0 to Spanish giants Real Madrid in the first leg of their quarter-final tie.
It was just Lampard's second game since returning as interim manager after Graham Potter was sacked and Chelsea have not won any of their last five matches in all competitions. They have also failed to score in four successive games for the first time since 1993 and have now lost more games this season than they have won.
