Everton boss David Moyes has told his players to expect a tough test against Blackpool this afternoon.
The Scot, whose side are unbeaten in their last six games in all competitions, insists that the Tangerines will be no pushover at Goodison Park and that his men will need to fight to earn their place in the next round.
"We're on a decent run," he said. "We have to keep it going if we can. It's going to be tough against Blackpool though. We are going to have to earn it on the pitch.
"If anybody's coming and thinking it's going to be [an easy] game, I'm certainly not. It's not the message that the players are getting here.
"Blackpool are a side who are in good form and doing well just now, so the message from us will be the exact opposite."
The Toffees came from behind to beat Fulham 2-1 in the previous round of the competition.
