Not a chance Laporta wanted to get rid of Messi. In some ways it's already tainting his legacy as he's now the man who couldn't keep Messi from leaving, people accusing him of choosing ESL over Messi etc it's all over twitter for example. So despite all the work he did previously, the pain of losing Messi and the way he left unfortunately won't be forgotten, even though it was the previous administrations fault.
I think ultimately all the ESL clubs were extremely arrogant in their approach to introducing it and misjudged the fan reaction because of the exclusivity granted to certain clubs and going against sporting merit. What worries me though is Real, Barca and Juve seem hell bent on running with this without an apparent plan B to stay relevant in case it doesn't fly.
