You lot are so closed-minded lol. Seems like everyone here is extremely ill-informed on Upa's quality. If you've only watched him play five times, then maybe refrain from commenting? His direct comparison is Akanji, and he's performing at the level Akanji was when we signed him. His physical traits are rare. He's still quite young.
People saying he's a liability on the ball? Are you kidding? Just say you only watched him against Man City and move on. He attempts nearly 100 passes per match, completes 93% of those. He has 7.09 progressive passes per 90, ranking him in 99th percentile of big 5 leagues. He's one of the worlds best passing defenders. Also, his progressive carries stat is 93rd percentile.
Akanji attempts slightly less passes, but completes ~same amount, has 5.53 carries per 90, and is 97th percentile in progressive carries. They are spitting images of each other at this stage, but Upa has plenty room to grow based off his physicals. Yes he's a bit rash and mistake prone, but that's less of an issue at RB than CB. Should mature with age.
Think he could excel under Pep. Walker is not the man he once was, unfortunately.
