None of us have any idea how well he did in training, so it's pointless to discuss that. Fact is that OB had a keeper (Arek Onyszko) they were very happy with until he got charged with assault. When he was convicted he was sacked and, as I said, people expected Lindegaard to takeover from there. OB managed to get Carroll instead, and although he wasn't a big name in England anymore he was still a big signing for a Danish club like OB, so it was obvious that Lindegaard was never going to get the chance. Lindegaard proved at Aalesund that he was a good keeper, so I think it's reasonable to suggest he would've done well at OB if given the chance, but he wasn't going to when they signed Carroll. I honestly don't see where he should've taken his chance at OB. Arek Onyszko did very well for them so there was no reason to change that, and OB was never going to not sign Carroll at the time given the chance.
Why do you keep saying he's done nothing to get praise? He did very well at Aalesund and his games for United have been good so far. People are simply praising him for what he's done, while you're suggesting he should be slated for what he hasn't done. I'm sorry, but that's fecked up logic.
I think most (myself included) very much expect De Gea to be our first choice next season and it'll take some massive mistakes to change that. Lindegaard won't get many chances, and Fergie might even play De Gea in the CC so he gets used to as many of our players as possible. I just think it's very odd to write off Lindegaard because of his age and because he hasn't played on a higher level yet. He's done well at the only club where he got the chance and he's done pretty well for United so far in the matches he's played. Many goalkeepers don't fulfil their potential until their late twenties, so I don't get why you're expected Lindegaard to.
