Your last paragraph was spot on.But they should at least consider the things that you quite rightly mentioned in your first paragraph. We've seen it happen plenty of times over the years. A lot of people love to slag players off without any kind of consideration to mitigating factors.
Vipi was a young lad who had basically just been made redundant, moving to one of the toughest leagues in football under a coach who didn't have the first idea what to do with him. Is it all that surprising that it took him some time to find his feet?
Despite that there was clearly potential there. More potential than basically anyone expected, maybe even those who thought well of him last season, but it was there if you were willing to look.
I’ll just add to that by comparing EG, who was “promoted” from league 1 to the championship, to most of the other players arriving from out of Britain, you can see the difference in the time it took to settle in. It is not only the game level itself (I think that Ronald was the only one who could play 90 straight away), it’s adjusting to a new country, the weather(oh, the weather), the culture, the food, the distance from the family..even to the fact that
around Christmas and new years, when many other leagues are on their winter break, in England you play double the games. It is not something that describes the championship specifically, you can find many examples even in the premier league.
The bottom line ( and the lesson ) is that patient is needed when it comes to foreign players. They might blossom immediately but if not, we need to breath deep and wait.
