Stubbs demands Everton focus for Cup semi
"We won't have a problem raising ourselves," Stubbs told evertonfc.com. "If we do, then we really have problems. It's a great game for us to go in and it speaks for itself.
The FA Cup loss to the League One outfit can be considered one of the shocks of the third round and Stubbs concedes the defeat was hard to take in light of the Blues' recent form.
He continued: "It was a major disappointment for the Club, for us as players and it's difficult to take any positives from it.
"There are no excuses. I'm not going to stand here and make them because there aren't any to make.
"We had the majority of the play but never created real clear chances.
"But the team that we had out on that pitch should - and no disrespect is meant - have comfortably beaten Oldham. There were five or six changes but those lads who have come in want to be playing regularly in the team.
"You come in to do the job that the manager expects you to do and if you don't, there can't be any complaints."
