Everton welcome Bryan Oviedo and Arone Kone to the first team squad after long term injuries.
Darron Gibson should start, but Seamus Coleman and Steven Pienaar are still missing.
Roberto said: "Every game ahead of us is one where we expect a good level of performance. It is important that we share the demands within the squad. But that does not mean we don't want to do well. We want to do well in that we want to win the game and it is important to have that competition for places.
"It's vital that we are fresh and we have the right players on the pitch. We expect to have a performance that is up to our standards here at Everton.
"Just because we are making changes doesn't mean we don't care about a competition. If anything, it is the opposite. It is a real opportunity for everyone in the squad.
"I believe our squad is capable of coping with different line-ups and ways of playing. For me, this game is very important because it will give us a lot of information about this squad ahead of the nine months of competition.
"You are looking at certain players who have been playing in the international break and have played two games with their national team.
"Certain players at a certain age can cope with more games, so there are many aspects that are important. You have to look at it on an individual basis.
"But we need to be able to cope with the demands that we have and the amount of competitions, so I am quite excited about seeing players that haven't played getting the opportunity, without losing the level of performance that we expect."
