Glenn Roeder felt the referee was "very petty" as captain Scott Parker and Nicky Butt were cautioned in the match at the JJB, a match that saw Wigan fined £25,000 for having six players booked.
Roeder: "I like to see a referee apply common sense, but I don't think he [Wiley] did in this game.
"He is a very experienced referee but I thought he was very petty.
"I was close to the situation when Nicky and Scott were booked, and neither of them have said anything that warrants a booking.
"They were unnecessary."
