I think the priority is signing Lukaku's near-enough replacement soon as. Then get the full backs in.
I'm calm at the moment and excited to see what we do. That credit facility is a game changer for us, if the player is keen we will bring them in this summer.
I've no idea who we bring in to replace Lukaku. I'd be happy with Giroud but we'd want wide players to put the ball into him. Other than Giroud, I've no idea where we can look for a promising young striker without paying through the nose for it.
Sandro was a real coup but I am not entirely convinced he's an out-an-out striker for us, his goal scoring record is quite good but a fair few were from set pieces. He might need time adapting to the league as well.
Rooney is a complete unknown for me. While I was against this move for personal bitter reasons my footballing brain does say the potential is there for him to come out flat out of the blocks and just will the goals in as this move could bring him some of his energetic self back. Or he could be crap and get himself crocked, who knows.
Still think we need one more option that isn't Niasse. Then get some wide players in because the squad is lacking depth there.
