And he's right.
I don't see any talented young forward coming here for the next 2 or 3 seasons (and hopefully longer) while MSN are still on their best. They all want to play and know they won't get many opportunities behind MSN. And it would be also crazy to pay 40M for someone like Sane or 80M and more in Dybala's case for a bench player. So our options are older players like Nolito (Lucho loves him and I think he'll get him in summer) or maybe Jonathan Soriano as a backup for Suarez (at the same time let Munir on loan or buy-back for 2 seasons and see how he develops; I still believe in him, but he needs to play and he won't get enough minutes here; if he stays he'll turn into a new Bojan with broken confidence). Also get back Denis Suarez (he can play midfield and LW, maybe also RW) and maybe Halilović for a preseason to see what he can do. But right now I don't think he's good enough and would prefer another loan for him, possibly to a better team than Sporting. Villarreal would be a perfect fit for him, I think.
As for Verratti, maybe in 2 or 3 seasons, when Iniesta will likely get a Xavi role from last season and Rakitic and Arda will also be over 30, but for now we are well covered in midfield and also have some good talents like Samper (he needs a loan to La Liga side next season), Kaptoum and Alena coming through La Masia.
