1: While I understand why you're comparing Mata to Hazard, Ozil and Silva, you have to understand the context of each team the player is playing within. Eden Hazard was playing for the champions, David Silva for last season's champions and Ozil for the team who had won the FA Cup twice on the bounce. All three teams finished above Utd. Mata, however, was playing for a team that was recovering from its worst season in decades and was still very much in its rebuilding phase.
Our most creative player last season was Di Maria, who created 'only' 51 chances. Juan Mata was second with 50. The problem last season was not Juan Mata not creating enough, it was our entire team not creating enough.
When compared with Herrera, Young, Di Maria and Herrera, players in the Utd team he should be realistically competing against, he scored more goals, was 2nd in terms of key passes, had the highest pass completion % and was 2nd in terms of chances created.
I completely disagree with your last sentence, too. I remember when we used to park the bus against Chelsea when Mata was at his pomp, and he still always tore us to shreds.
2: You're asserting that
one player is responsible for how the entire team plays, when that player is playing for the absolute 'system over individual' manager?
Unless I'm misunderstanding what a "Successful Take On" is according to Squawka, Mata actually has a higher % of them per game than Young?
The entire paragraph about his strength is based on nothing. You've backed up your claim that he will lose possession two or three times a match in dangerous positions with nothing, he played about ten minutes against Leicester and it's incredibly harsh to use somebody's pre-season form against them - it's pre-season.
His height hasn't been that much a problem for us. We don't use the crossfield switch of play that much - any long ball we do is a lump towards Fellaini.
3: Ashley Young's workrate isn't actually anywhere near as good as you think it is. In terms of average distance covered on the pitch per 90 minutes, Young is the 8th hardest working player.
Juan Mata is the hardest working player, and by quite a distance.
Although his tackling and interception stats won't be as good as Young, a player who has played parts of the season as a full back and wing back, Mata has improved immensely on his defensive game.
And you say Sanchez and Hazard ran riot down our right flank, but what's this based on? We lost to each team once - against Chelsea Herrera let Hazard run and he scored, and Mata didn't get on the field when we lost against Arsenal. And it wouldn't be Mata's job to mark Hazard or Sanchez anyway, that has always been the job of the right back. For instance, if you watch our games against Arsenal, LVG assigns Valencia to aggressively mark Sanchez and to even follow him around the pitch.
Mata's position isn't tactically obsolete, in my opinion. Our best football last season was borne out of his relationship with Herrera, when Mata was deployed on the right and allowed to drift. He's a brilliant player with a brilliant footballing mind: he understands at every point what position he should be and what his next pass will be; he knows how to time his runs into the box, hence why he's such a consistent goal-scorer; and he knows what's needed at any given point in the game, whether we should speed the game up or slow the game down. The problems you're criticising Mata for are either issues we had throughout the team for the entire season or issues you're inventing.
