@ Sumlit:
The results speak for themselves. So, as much as I used to agree with your arguments about Alexis not being suited to our game, times have changed and so has the general consensus.
Tata has integrated Alexis' unique style and aligned it with our current system, whereas Tito and Pep basically threw him in the deep end of the pool. He sank because there were complex theories being applied that he knew very little about and it was obvious that proper care was not taken to bring out the real Alexis. That coupled with untimely injuries meant the project was failing.
Fast forward a few years. Alexis believes in the cause thanks in part to Tata and maybe a little of the young South American partnership he has with Neymar (I do agree with the person who stated Alexis' game elevated when Neymar was signed), the overall game of Alexis has evolved into something entirely suited to Barca (Goals, assists, link-up play, deadly crosses, work rate and defense, etc). There is little one could argue that Alexis does not offer in terms of tools. You can nitpick any one of our players. For example, Messi is short and is weak at headers and set pieces, Cesc is slow in transition, Montoya is weak in attack, etc etc. Does not mean they are not suited. Once they are integrated, they are part of the squad.
It seems to me that your opinion may be outdated.
