There's a long season ahead, we cant predict what would happen. God forbid if Oscar gets injured.. Then Mata can have a lot of playing time. Or maybe he'll just prove to be betther than Oscar. Or maybeee things will stay the same, he'll have some playing time but wont be 1st choice and he'll choose to stay. And ofc there's the option of him losing his place completely to Oscar. The thing is, and I've said it before, I feel like Mata is a player who needs to be watched for quite some time to impress. He might not do anything that looks spectacular (just passing the ball, moving it around..) for around 60min but then give that one pass that can win the match. He has around 3-4 of those passes in a match I'd say. And it's not like he's not doing anything else in the rest of the match, he moves the ball to where it SHOULD be moved, he helps the game flow. BUT, it might not look like something special for some people, for them it seems like "anyone can pass to the person next to him" or whatever. With Oscar, he dribbles more, has more shots, he's more of the type of player who's gonna try to create something in each play, the kind of player whom you'll find a lot of Youtube videos on. You only need a few minutes to see what a talent he is. I hope you guys get what I mean, because it's quite hard for me to explain, especially in English.
