We are a business, the sooner people realise this the better.Surprisingly, the club does not exist to please fans. It exists to make money, like any business. If the manager and the board decide that selling Che will ultimately help up achieve this goal, then so be it. 3m for a very raw player with very little game time or experience, regardless of his "potential" would represent good business from a buy low, sell high perspective. I like Che and think he could do well at united. You said it yourself, he hasnt performed that well this season, imagine if his form never "gets together" and he has 1 good game in 5 (purely playing devils advocate) - then 3m would represent a good deal.
For the record, I hope he improves and I hope we do keep him for many years if he continues to improve but the flouncing if he was sold for 3m would be amazing to watch.
