Kevin Campbell believes Everton's thin squad is the main factor behind his former club's faltering bid to break into Europe this season.
Campbell, who played for the Merseyside outfit between 1999 and 2005, was questioned over how Carlo Ancelotti can guide his team to taking the next step.
The sheer amount of injuries forced boss Ancelotti to name a host of youngsters on the bench at Brighton - and Campbell says reinforcements are needed to improve.
'When you have made the changes that they have done in midfield, you take the Cortina engine out and you put the Rolls-Royce engine in,' he told Sky Sports.
