Yeah, media will go crazy.
I think his first job will be a financial audit to see what situation we're really in before they'll make any serious sporting plans. In the meantime he'll talk with Messi and potentially our other players/their agents whose contracts are expiring next year like Fati, Ilaix and Pedri. I'm not too affraid to lose them but it would be nice to see them all tied up to the club on longterm contracts.
That said, Alemany, Cruyff and co. will surely get in contact with agents of potential targets. It's possible that Laporta has already talked with Raiola about Haaland (like it was rumoured) and maybe some other agents but he couldn't really do anything before he was officially elected. Now his people can go to work but tbh I don't expect much to happen on that front before the end of the season (or at least until we're still alive in the league). Raiola will surely also try to drag Haaland's transfer saga for as long as possible to get the most money out of it unless Haaland is clearly prefering going to one team and that team only (which I dont' believe at this point).
I wouldn't be too surprised if they would confirm Eric Garcia's signing relatively soon though. His contract is probably only waiting for Laporta's signature.
Pre elections is also the perfect time to talk with agents off the record, without infringing on "tapping up" rules. I expect alot of the leg work on who they are interested in and the type of fee's the clubs would be willing to accept have already been done by Cryuff/Alemany.
