"Adam is a poor man's Alonso" doesn't really ring true for me. Apart from the fact they both like to play a long ball, and they both like to shoot from the half way line (Adam does this annoyingly frequently), I don't really see the similarities.
One of Alonso's greatest strengths is his impeccable positioning and reading of the game, as well as his ability to always pick the right pass and to be available for his team mates at all times.
As far as these attributes are concerned, Adam is not even in the same Universe as Alonso. He always seems to be trying to force it, and go for the killer ball. The less said about his positioning, the better, and his ability to find space to offer for an easy pass appears limited. I do feel that Adam has it in him to be a good player, his technique is superb, he has a great passing range and a hell of a shot. However, he has an awful lot to learn, and, at the age of 26, whether he will ever learn the key traits to make him a really good player is doubtful.
At the moment, if we want to accommodate him into the side, I feel we need to play at least two other players to cover his weaknesses. This would be acceptable if he was an outrageous talent, such as Gerrard in the 2008/09 season. Unfortunately for Charlie, he's nowhere near that level, and if we're going to set up a system to get the best out of any player, it should be Suarez.
