@footyfan. You are probably somewhat right about him saving himself for the world cup, so we can at least credit Lucho with moving Messi out wide again.
Perhaps best of all Lucho has past under-performing players upping their game, Pique in particular. Masch is probably having his beast season at CB ( I'll eat my words for the shit I gave him before ) and low and behold I think Busquets has looked much better recently.
Perhaps most importantly Luch is a ballsy coach, he's willing to play counter attacking football and he puts results before style. I don't why Tata seemed to give up on his inital tactics but Lucho certainly wouldn't do the same. It's still all very early though and we a yet to really perform well away from home against big teams excluding the Calderon where we took a 1-0 lead.
He was really off form during the WC.He surely wanted to win,but did not press,he moved a little and generally was not sharp at all.Maybe he had an injury or something...
It annoys me that some people thing he had a bad world cup. He absolutely did not. He dragged Argentina to the Quarters and after losing Di Maria he was pretty much alone up front. When he would get free from being triple marked he looked really dangerous and he set up 2 chance for his team mates in the final. He did not have a bad world cup.
