EN Foster admits he had to force himself to watch a video nasty of his derby disaster. The United keeper was downcast and his initial reaction was to ignore the media coverage of the errors against City that almost cost the Reds victory in the 4-3 showdown. The 26-year-old bounced back with a clean sheet at Stoke on Saturday but reveals it was a traumatic aftermath to his first ever Manchester set-to. "After last Sunday I pretty much buried my head in the sand to be honest," says Foster. "I didn't really want to watch the television and the next day the papers, there was no way I was reading any of them. "But when we got into training you have to face up to it. You have to look at the replays and analyse it and learn from it. "Our goalie coach Eric Steele has been on at me all week and has been hard on me really but I needed that and I like to think I have learnt from it. "I am absolutely delighted with the boss for sticking by me. Last Sunday was a disaster for me personally. It was a great day for the team but for me I was absolutely gutted after it. "I was the only one in the changing room with an upside down smile on his face! Foster thanks "You are going to have those days as a goalie sometimes and you have to keep them to a minimum. I have to say a big thanks to the boss for sticking by me. "The more you play the more the concentration and consistency comes. That is what comes from playing. Edwin Van der Sar is a typical example of Mr Cool. He is a fantastic professional and he is, someday, what I want to emulate at Manchester United. "He is exactly what I am aiming to be for years to come." Foster, however, looks like he'll have a fight on his hands for the gloves for longer than we all thought. It was widely accepted that this campaign would be Van der Sar's last before retirement. But the Dutchman, who'll be 39 next month, insists that's not set in stone. "I don't want to pack it in. At the end of my holiday this summer, I was itching to go back to the training ground," says Edwin who is around three weeks away from a return after August surgery on a finger. "I have the hunger to win the Champions League again. It does not matter that I won it in the past. The season could not start soon enough for me and it was unfortunate I got injured. "I think Ben has done well as my replacement. But I still work as hard as all the others at training, whether I'm old enough to be their dad or not." What do you think? Have your say.
