Calm down mate. Losing players happen. Don't know why folks get so worked up about it.It's not a good look on Edu though as then he gets a reputation of a guy that can't close out deals for Artetas number 1 targets.
With Xhaka and Partey potentially leaving, we are woefully short of experience and leaders. In my opinion Rice should be 1 of the pillars of Artetas team, a future captain and leader.
So you sort out your pillars first, and then add your Havertz or the like after that.
Everyone misses out on players, it's disappointing but you get over it quick. Vlahovic, Mudryk, Martinez etc. But I just get the feeling that this one is different, it really could define Artetas era in my opinion.
I personally think Rice is good, but I'd rather have Szoboszlai personally. There are other good players. Just scout and attack your needs.
