I understand that Jorginho is the wrong side of 30 and cannot replicate Thomas Partey’s role. But with Mohamed Elneny facing an extended injury layoff, and Sambi going to Crystal palace, Arsenal remain short in holding midfield. It’s not really a replacement for Thomas Partey, but bringing in another midfielder to thicken the depth. Honestly, it’s a good signing, €12M for a proven EPL player that brings in depth and experience to this squad isn't too bad. And it's only a short term fix as the contract also suggests.
To be honest, I don't expect much from Jorginho. however because Arsenal didn't get what they wanted from several of the midfielders they had their eye on in the January transfer window, in particular failing to sign Caicedo from Brighton. Jorginho, could be an option to replace Thomas Partey. at least, Jorginho can be relied on by Arteta considering he has a long experience in the Premier League.
According to rumors, the arrival of Jorginho clearly made coach Mikel Arteta happy because he is an admirer of the player. however, it is reported that the voice of the Gunners supporters broke because Jorginho had difficulty showing his best performance with Chelsea. Meanwhile, if you look at the skills he has. Jorginho has a plus, he has more accurate passing accuracy than Partey and Caicedo. apart from that, whatever Arteta does. as a Gunners fan, I hope he can perform well with his new team.
