Just checked and Bruno Fernandes has a 5.1 average, which is even lower than Jadon Sancho's rating.
The bigger issue is, that people understand the rating system differently... Just like you who seem to be suprised to see Bruno have a 5.1 even though that isn't a bad number at all. A 5 should be a performance where the player is either not doing anything wrong but doesn't stand out positively or it should be for a performance where the player has a lot of good moments but also a few shockers. A 5 isn't bad at all over a full match, let alone multiple ones with really bad performances all over the team.
But it seems like certain moments in matches skew the ratings (which is of course understandable, but I don't get the extent) a bit too much - like yesterday when people were rating Bruno with a 7 or even higher for a world class finish that was surrounded by not all that much of the bare minimum. Same for Casemiro against Bayern who struggled quite a bit but made two late goals out of nothing.
This just seems revisionist. Vidic and Rio were crocks for their last 3-4 years and Evans played a lot and in big games. I believe he had a big run in our 2008-09 consecutive clean sheet record. It was mainly Evans and Rio CBs in our last title win.
He had a poor season under Moyes and LvG wanted a left footed CB and generally sold players awfully. But by then he was an established player who had a bad season in a difficult environment.
They were rocks but they were getting old. Just like not too long ago, because of their pace, the team had to play with a deeper line which was an issue. Remember the famous 3-2 win in the cup where Fergie brought Smalling and Jones for the two big names and we changed the game. I am more than thankful to have witnessed Rio and Vida in their prime for our club but a top club has to move an. Same for Evra and RVP. The issues back then were Hernandez, Rafael and Wellbeck who, while not being great at all, at least gave us intensity and workrate. This dropped ridiculously down and you could argue that apart from spells, it hasn't fully recovered even today. That of course isn't just because we lost those specific guys but the recruitment wasn't able to bring in people who could provide that workrate. Another big issue was that we lost the spine of the team in this phase... Which again isn't solely down to some players being moved on - the issue was that Fergie clinged on a few players before he stepped down. Rio, Vida, Evra, Giggs, RVP even Carrick and probably one or two more were the spine of the team, leading figures who delivered every game to a good degree. We should have found players to take over from them but we didn't really. Which then resulted in falling down a cliff when they were gone during a relatively short period of time.
