Incomings - Arsenal
Jorginho - £12million in total
After appearing to miss out on Moises Caicedo with Brighton refusing to budge and Edu and co refusing to overspend, the Gunners have turned to their cross-city rivals for midfield reinforcements.
In a move bound to upset large groups of Arsenal fans online, the North London outfit is set to complete the signing of the 31-year-old Italian before the window closes.
The reported fee of £12million seems like a good deal for what will be an extremely experienced bench option to help push Arsenal over the line.
The annoyance from fans will probably stem from this looking a bit like a panic buy from the board.
The track record of Chelsea players signing for Arsenal is not excellent, so Gooners everywhere will be hoping Jorginho will be able to buck that trend.
Leandro Trossard - £27million in total
After the asking price for Ukrainian wonder kid Mykhailo Mudryk rapidly approached €100million the Arsenal board seemed reticent to cross that financial line, so they walked away.
While clubs like Chelsea and Manchester United are seemingly happy to splash whatever cash is needed to secure players, Edu Gasper has limits to what he values transfer targets at, something I think should be admired in the market we currently find ourselves in.
However, with Mudryk gone, the league leaders still needed to find a suitable player to add wide depth to the squad.
For less than a third of the price Chelsea paid, Arsenal secured the signing of Belgium international Leandro Trossard from Brighton and Hove Albion.
A Premier League-proven winger that has already scored an Anfield hattrick this season is an excellent deal at that price.
The forward was brought to the club as depth, but if he can keep his excellent form going, he might find himself starting more games as the run-in heats up.
Jakub Kiwior - £21milion
Of the three signings Arsenal has made thus far in the window, the purchase of polish centre-half Jakub Kiwior from Italian side Spezia has been the biggest surprise.
The left-footed defender has been signed to provide more competition to in-form centre-half Gabriel and adds great depth to the whole backline.
The Polish international was in hot demand from other clubs in Serie A, with reports claiming that both Juventus and Milan were eyeing up transfers for the young Polish international in the summer.
