It's not unfortunate at all, he does it all the bloody time. When he came on against Spurs first day of the season, we went from having no attacks down our right flank, to him being caught of position like 3 times in 15 minutes. There were a huge amount of goals that "coincidentally" came down big gaping holes in our right flank last season in big games like Monreal ghosting in to score in the FA Cup (then a complete feck up with the backpass to lose us the game), City's first goal in the 4-2 (there was also a moment where he made the exact mistake as vs Wolfsburg, but because he was fast enough to get across to Aguero everyone thought it was good defending
), Hazard's goal at Stamford Bridge, Everton's goal where he just let Mirallas run through and this is just off the top of my head.
Many of these aren't obviously his mistake, but his ball watching and positioning is just awful and his lack of defensive instinct just causes panic and means that everyone loses their shape trying to compensate. I recall Smalling playing as a RB pretty much half of City at home last season, and also getting sent off because Valencia had gone awol and let Milner run in behind him in the away game. I bet my bottom dollar that Smalling much prefers playing next to Darmian than Valencia.
The reality is that Valencia should not be at this club. He hasn't been any good since 2012. He's so shocking in his original position that we have to play him as a fecking defender, where's he's still shocking going forward and apart from being big and fast can't defend for his life. I can see why Valencia was defended heavily by some, but now people are realising he's just shockingly bad. I mean he used to be one of my favourite players, no nonsense, traditional winger, no-ego, no-emotion machine at his best terrorising full backs over and over with no respite, putting goals on a plate for Rooney. He came back from a horrific injury to be our player of the season
and displace Nani in the form of his career with us. But since then he's been shocking, and I think he's developed just a terrible mentality where he doesn't want to take any risks - the type of player who feels burdened by the Man Utd no 7 and goes back to 25.
He's just not a RB either, maybe RWB where he doesn't need to defend or attack he just should be gone. I've honestly never seen a player consistently bad for three seasons still outlast so many other players and still get games for us. I've pretty much said everything about him in the past, I spent half of last season pointing out to those in denial but a substandard RB an RW he is, I'm just shocked he's still getting games for us. Which is a shame, because as I said before, I used to be a massive fan of him.
