Everton could only manage to pick up a draw against Watford yesterday.
Roberto Martinez has told BT Sport that Watford could not deal with Everton midfielder Ross Barkley.
The England international was substituted off in the second half of Everton’s match at Vicarage Road, after he picked up an injury.
And Martinez admits losing the attacking midfielder was a blow, as he had been so influential in the first half.
"He had a knock and he couldn't really stretch his legs in the second half," the Spanish boss said. "That was a real disappointment as I thought he looked really fresh.
"He created a real problem to the Watford defence, and I don't think they could cope with his movement and his understanding of the space.”
Everton did not manage to pick up a win against Watford, as their poor run of results continued.
Everton fans in attendance unfurled banners which asked for Roberto Martinez to be sacked yesterday.
Everton’s poor performance against Watford was compounded by the news that Phil Jagielka could now be set for a lengthy lay off.
"Jagielka is probably a bigger worry [than Barkley],” Martinez added.
“He felt his hamstring and Phil doesn't get injured that often. When he asks to come off it is a worry.”
Everton’s next match comes against Alan Pardew’s Crystal Palace side at Selhurst Park.
