Paul Dickov is relishing the prospect of Latics taking on the best as Premier League champions Manchester City visit Boundary Park tonight.
City have yet to confirm their side, but Latics' manager expects some of their stars to feature.
City are currently on tour in the Far East, but their Euro 2012 players were given extra time off.
Dickov said: "This is the biggest test of our pre-season as they don't come any bigger than the Premier League champions.
"I would expect some of their top players will feature so it will be a fantastic test for us, both fitness wise and tactically how we deal with them."
This is the penultimate friendly before the competitive action kicks off against Sheffield Wednesday in the Capital One Cup on Monday, August 13th.
And Dickov expects his players to up the ante as the competition for places intensifies.
He said: "It is up to everyone to impress me as the team will be picked on merit.
"There are two friendlies left for all the players to show me what they can do."
Dickov is delighted with the way pre-season has gone in terms of the fitness of the players as well as performances and results.
An added bonus is that everybody has a clean bill of health so far.
