“Caicedo was offered to United for 5m just 3 years ago”
That may be the case but you can’t assume he would be the player he is today. Every environment is different. This idea that he would be the same player he is today is one of the misconceptions of twitter that drives me mad

In the 1950s, Charles Reep published in the News Chronicle findings of less than three passes leading to a higher probability of a goal being scored. While Reep's findings are now disputed, it led to England's identity of Long Ball play. Now, in 2020, how much has changed?

I can save Manchester United the time and effort of hiring someone full time. The player they are looking for is named Dean Henderson. He won’t cost anything, is arguably better than De Gea right now, AND helps the homegrown quota.

FC Porto have gained a reputation of developing young players and selling for massive profits every summer. Since the 2010-11 season, club president Jorge Nuno Pinto da Costa has generated a net income of a stunning €310,220,000 in transfer dealings. Shrewd business.

Really have to feel for Arsenal and their small budget, it’s tough to be competitive when you can only spend 150m on the market and another 130m+ on wages.
It's been weird to watch Arteta - who is a bright, but still fairly young head coach - learn new lessons on the job every season.
This year obviously very much about squad management, but also... it's still REALLY hard to compete at the top of the PL + CL on Arsenal's budget.
