Right, if we shouldn't try to accomodate Alexis at all, who's your suggestion for a better RW who'd be content with never being allowed to leave the flank, and still produce heaps of goals and assists?
If I am not mistaken, Alexis plays awesome when either Messi or Neymar are injured or off the field.
So, most of his Goals come in matches where he is not our 3rd attacking choice (behind Messi and Ney), but when he is our 2nd key man in the attack.
Or, in matches when we win 6:0 or similar.
Whenever are all our players fit, and when he is playing alongside Messi and Ney, our players usually pass the ball more to Ney and Messi in Goalscoring chances, so he is a 3rd option, let's say it in that way.
Whenever he is the 3rd option, he plays not so good. He trips over the ball or just passes the ball to Messi all the time.
He is just average against stronger opponents when Messi, Ney and Iniesta are all on field.
(People will now say: what about his wondergoals against Real and Atletico..) Those were good, but too rare in bigger matches.
Imo, there are other other players who could play better and more consistent as a 3rd wheel in our attack, alongside stars Messi and Ney.
In shorter, Alexis is hiding on the field, tripping over the ball and just passing to Messi when he plays with Messi and Ney.
When one of them is gone, he is much better, more confident and scores more.
But again, since our team is built around Messi and Ney, and if we assume that they won't get injured, then we will usually see that weaker side of Alexis, when he is poor with those 2 on the field.
Again, guys who will reply now: "He scored 21 goals", please go and count how many of those Goals were with Mess-Ney-Alexis on the field.
And how many of those were not against weaker La Liga teams in 5:0 and in similar trashing.
In other words, how often he scores, assists and play well in bigger matches, with Messi, Ney and Iniesta on the field?
