Hull City boss Phil Brown accused Arsenal counterpart Arsene Wenger of getting goalkeeper Boaz Myhill booked during last night's bitter FA Cup clash.
Brown was furious with Wenger as he felt the Gunners boss was attempting to get his players booked for time-wasting, and he believed William Gallas was offside when he struck the winner in the 2-1 victory.
Brown felt Riley "succumbed to local pressure" in the second half after his players were jeered for time-wasting.
"Mr Wenger decides to join in and the result is my goalkeeper getting booked in the second half," he said.
"I can't say what went on at half-time, I have no idea."
He added: "Arsene Wenger got my goalkeeper booked. You call that good management? He was complaining about time-wasting."
Wenger was upset with Myhill time-wasting in the second half.
"If I asked you if their goalkeeper wasted time I'm confident that you would say yes," Wenger said.
