I don't think that is true. That is dependent on how you want your no.10 to play. It's very interesting you say that is what our no.10 should be, yet we are currently playing Depay there who will absolutely not do that.
I think a player like Mata actually becomes even more important when there is no space to exploit because he has the intelligence and know-how to find those small spaces. And when he does, he will get assists and goals because he doesn't faff around.
I don't deny that Mata being the creative hub of our team isn't the best strategy. But what I do know, is that against teams that are parking the bus, and we are dominating, then we can definitely accomodate Mata in that position and add the creativity around him a-la Herrera.
Also for the record, I am not opposed to him being on the right. I think if we scrap this notion that someone on the wing has to be a winger, then actually there is a good role for Mata there as someone who roams inside and takes up positions on the inside rather than beating his man on the outside. Especially now that we have a real right back and there isn't a significant amount to worry about with him going forward in this scenario of a team sitting back. I just overall feel he would be more effective in the middle.
Fair enough. I haven't seen much of Memphis, but I assume that he dribbles players and holds the ball better. He's also a more physical player, but more of a risk taker. It also remains to be seen whether Memphis will indeed play there long term.
I think that when there's a lack of space, Mata will go missing, and play safe. The emphasis would then be pushed towards the wingers, and essentially Mata would just be there to score goals. I could imagine plenty of frustrating games, where Mata appears to go missing. And he's either really deep or really high, but never in the right spot. And the ball would pass him by, until he drops deep and plays a simple pass (that carries the team nowhere) or becomes the highest line of attack, which defeats the purpose of the formation.
Mata is good at finding space in the box, but in a slow possession game, the biggest issue is getting the ball around two banks of four and
into the box, so you're advanced midfielder needs to be the one holding the ball, dribbling to create space for others, and carving teams open - not simply putting the finishing touches on moves. The actual space where your 10 should be is the exact area where Mata struggles to make an impact.
It's almost crazy - because he's obviously no athlete - but he's significantly better in a team who break and do less dominating of the ball in the opposition's third. And that's partly why I claim Chelsea being mediocre led to him hitting higher stats. They not only played less-dominant football, they also didn't ask him to do much defending.
The Champions league is largely irrelevant, because they basically just defended for dear life, and got lucky. And he wasn't a key man.
One area where Chelsea didn't falter was their threat from set pieces, and I'd be interested to know what percentage of his assists were from set plays.
