Roy Keane says he is getting tired of people saying Man United are showing signs of potential while not actually winning football matches.
United drew 0-0 with local rivals Man City in a drab Premier League encounter at Old Trafford on Sunday.
Both sides struggled to create clear-cut chances and it was the second time in the space of a week that United have failed to find the net.
'The manager is going to stick with it,' Keane said after the game. 'That's the gamble he's taking. If he's not getting football results, we're talking about next year when he will no doubt get an opportunity to get players in the summer, we will be able to judge him better.
