“I have only found Sir Alex really helpful for me,” Moyes told reporters ahead of Sunday’s Premier League trip to Aston Villa. “If I have needed any advice I can pick up the phone to him. “I will have a call maybe once every two or three weeks and he has been very good. “I don’t see him regularly. He comes to the games but he is a director now so he is entitled to do that. “We bump into each other now and again and I will say hello after the games. “He doesn’t come to the dressing room before or afterwards. A lot of the directors do but Sir Alex keeps away from it. “I have no problem with Sir Alex whatsoever.” Press Association Manchester United manager David Moyes has dismissed Roy Keane’s claim that Sir Alex Ferguson is still trying to exert influence at Old Trafford. Keane made his observations during the ITV4 documentary with Patrick Vieira, screened earlier this week. However, Moyes said any communication with Ferguson tends to be instigated by him – and that his predecessor does not even visit the dressing room to see his old team on match days.
