Barcelona coach Luis Enrique mocked Malaga boss Michel after victory over Osasuna on Wednesday night.
After the 7-1 win, Enrique was asked if the Catalans could rely on Malaga beating Real Madrid in the last game of the season.
Los Boquerones are coached by former Real player, Michel.
"If my grandmother had wheels, she would be a bicycle," he said to reporters, indicating that he had no confidence in Malaga springing a surprise.
