And the next time Martial (if he improves), Micki, Mata etc. are getting new contracts, they'll go past him in terms of salaries.
Didn't say opinions of United fans should be ignored. I wouldn't use the ratings as a base for an argument though. All you need to do is wonder around matchday threads (I never do that anymore) to see how emotionally invested posters are during and right after a match. So I choose to ignore the Caf ratings when discussing a player's performances. You choose otherwise, that's fine.
I don't go into matchday threads either - too hysterical - I'll watch the match and usually watch all or some of it again and then make a judgement on all the players and rate according to my valuation of their performance. I don't care who scores as long as United win.
I find stats misleading as players can have one or two moments in a match and then be totally invisible for the remainder of the time, which is my biggest gripe with Lingard. See your latest stats you posted which shows Lingard ahead of Zlatan in that stat, if Lingard swapped positions with Zlatan we wouldn't even be 5th or 6th , we'd be 15th/16th.
Take yesterday, Lingard didn't have a bad match but he had two shots, had one decent pass but you look at his overall play, a couple of times he asked for the ball and got it, when he got it he had no idea what to do with it as he doesn't have the technical ability to play a longer or difficult pass. People claim his running is a big plus but there were two instances at least when he made completely the wrong runs , once with Zlatan and once with Pogba.
His speed is over-rated as well , in recent matches you have players sprinting away from him, most remarkably against Boro when Mata of all people outsprinted him.
Regarding salaries , yes there are/have been other players that are overpaid, but those were considered as first team starters like Basti , Rooney now , Young is another example but when he was signed and with his current contract he was a first team starter, Lingard still isn't or shouldn't be considered as a first team starter. He will end up like Young being a bit part player on a high wage and other clubs wouldn't be able to afford to sign him but has never been or likely to be considered a first team starter.
When other players in his position get the ball, you're expecting something to happen and excitement builds, when Lingard gets the ball the expectation is that he'll lose the ball, pass the ball back or have a poor shot, occasionally he will do something but usually it's because the opposition pay little attention to him because he is the least likely to cause them problems.
