Arsenal have been very busy in the transfer window in terms of both buying and selling players. They let go of two good players in Wilshere and Cazorla and Unai Emery has been pragmatic in the way he managed to replace them, and has still managed to add more depth and steel to his squad.
3. Lucas Perez:

He spent the whole of last season on loan at Deportivo La Coruna and managed to start 35 games in the La Liga. He managed 8 goals in that process and while he has shown glimpses of what he is capable of during this loan spell, he has not made a compelling argument as to why Unai Emery should stick with him for one more season.
Fiorentina have come up and asked for the striker and the Arsenal board were more than just happy to negotiate a deal for the Spanish striker. Rumors suggest that Fiorentina have secured the player for a decent fee of £7 million.
2. Chuba Akpom:

The deal has already been laid out according to rumors and Arsenal have inserted a 30% re-sale clause in his contract. The deal will be completed for just £1 million. He was already spotted at the club’s medical center and has already undergone his medical.
1. Aaron Ramsey:
This rumor came as a surprise to many, but as the days go by, there seems a lot of truth to this. Chelsea owner Abrahimovic and new boss Sarri have earmarked Ramsey to be their marquee signing this summer. More than the acquisition of the player, Roman wants to prove something to his London counterpart.

A deal in the region of 30 million is seemingly on the cards for Chelsea, but it all depends on Arsenal as it is highly unlikely that Ramsey will hand in a transfer request. It is also possible that Arsenal chooses to stick with the player for the last season of his contract and let him go for free.
