Wigan Athletic skipper Gary Caldwell has criticised Arsenal captain Robin van Persie for not shaking hands at full-time on Monday night. The Latics stunned Arsenal 2-1 at Emirates.
The pair clashed just before the final whistle and Caldwell said: "To be at a great club like Arsenal you have to be a bad loser.
"But you also have to have a bit of dignity. When they beat us 4-0 at our place I shook everybody's hand and I expect the same back."
