Think the real plan is to get him on loan first then Debuchy, Anita and Douglas on transfers. We'd solve all depth problems and improve our starting eleven while staying within our budget this season. Next summer I could foresee us needing strikers, and that's when we would probably take up the option of buying Carroll for A) A much cheaper fee, B) when he has indeed proven himself to be what we need and C) when we have a fresh new transfer kitty to work with at the start of next season, which could be boosted if we perform in the league and have a long cup or European run.
