Valencia played well as a fullback for a large part of last season, and wasnt just put into the team for no reason.
Look at his thread from last season. It's merely the case that a lot of people wanted him to fail, and when he did make a mistake against Arsenal, people came out with the pitchforks. Just check the general trend of comments yourself
Rafael is a good player, a tad overrated on the Caf though. He's got his own frailities beyound injuries.
Surely Darmian should get some patience as he's only 6 months .
I fear a lot of the hate stems from the same hate Valencia got last season. It's because of who they replaced. The Rafa love in means that whoever we got in was bound to be scrutinized beyond reason.
Valencias 6/10 performances we all remember, here and there 7/10 and shocker from time to time, we got used to lower standard, if you watch how Rafael played, how proper modern right back plays in fact you would see the difference but I have comfirmed it here many times people have short short memories, and are able to cirtisize players for being injured and in the end just settle for lower standards. I wasn't critisizing Valencia much he did his best there but his inability to use his brain was absolutely unpardonable and I was furious we couldn't use that right hand side even more with Mata and Herrera in form.. If Darmian will ever reach the level what Rafa showed us unfortunately only for two seasons due to injuries, he wasn't struggling with any of the top players, like Ronaldo/Bale, Hazard defensively and showed like three times more in terms of attacking.. if darmian ever be close to that level I will consider a success..
Yes people love rafa for his dedicated etc. but also like to remember his world class performances, it's the other half of people who only remembers one rush challenge there and a lot of time being sidelined.
Anyway it's just a waste of time to explain some people this frustration from lack of quality at fullback position, some people get excited from very little..
