The improvements cannot stop there, though, and Arsenal must improve their squad ahead of next season.
In that vein, we have rounded up all the latest transfer news and rumours.
Arsenal are being linked with a move for Sparta Prague frontman Adam Hlozek.
Hlozek has scored 12 and assisted 15 so far this season, netting a goal in each of the Europa League and the Conference League.
Bayer Leverkusen have also been credited with an interest, and he’s said to worth around £16m.
Arsenal are keen to raise a big chunk of money from player sales this summer.
That’s according to the Mirror, who claim the Gunners want to bring in as much as £60million from outgoings.
It’s claimed as many as nine players may be forced to contemplate an exit, with Nicolas Pepe the most likely to be sold.
Crystal Palace are being backed to move for Nketiah ahead of the striker’s contract coming to an end.
Arsenal are said to be trying to keep Nketiah following a fine run of form from the youngster towards the back-end of the season.
But The Telegraph now say Palace are lining up a move for the 22-year-old as they look to build on a fine campaign under Patrick Vieira.
