I will try to add a more sober assessment on whether Berge would be interesting for us, and maybe also try to read INEOS' mind why he's at all being considered. My stand would be somewhere between the "absolutely not" and "go ahead".
At young age, Berge - along with Ødegaard and Haaland - was seen as one of Norway's most promising talents, and already when playing for Gent at age of 19, he attracted a lot of interest from bigger clubs. At Gent, however, he had a serious set-back in his development when he was out for almost a full season (17/18) with a torn muscle bundle. The following season, he lost more than 2 months with knee and calf problems. After Sheffield United signed him before the 20/21 season, he suffered another setback with a hamstring (surgery) that put in out of play for 3 months, and then the season after, we was out for 2 months, again with hamstring problems. After each injury, it took him a while to get up to speed, and only last season at Burnley, we started to see more of what he is capable of when staying fit, and of late, he has started to perform better and better also for the national team. Today, he would be one of the first names on the team sheet, along with Ødegaard, Haaland and Bobb.
There has always been a feeling around Berge, that he possesses an unreleased potential which has been hindered by his injuries. His injuries alone, is an argument for not signing him, because despite of him staying fit last season, he has a history of being injury prone, and he might not survive Ten Hag's "survival of the fittest" approach. However, if he stays fit, he obviously has the talent to become a top player, and his unreleased potential - along with his stats - is maybe the reason why our recruitment team are having a serious look at him.
In the end, if would be a gamble, but I don't share the opinion that he necessarily would be a bad signing for us, and that he under no circumstances would improve our team. There is a reason why United have been in contact with this representatives, and there is a reason why INEOS may want to sign him for the right price. For 15-20m, I think it might be worth the risk.
