He's only 18 and will improve physically, where his acceleration over the first few yards will improve once he gets stronger. And once he matures physically, I believe we'll see a even better player.
I hope we have him working with a sprinting coach or something because my god he once again looked slower than christmas out there!
Gravenberch dribbled right past him multiple times, and Mainoo didn't get near him when "chasing" back.
This sucks for him because he is amazing when we have the ball! That reverse pass to Garnacho was incredible! But how can you play as a number 8 in the Prem if you're running in sand?
Seeing a number of posts referring to this, particularly in terms of recovery runs, but what is actually evident is that whilst he's mentally and technically able, he doesn't have his adult stamina and power yet and one of his clear vulnerabilities until he does, is that he can be run off and outworked because he is running out of steam and needs more time in recovery per sprint and aggressive action than those who are in their full adult body.
It's not a coincidence that he sometimes looks like he's running in treacle and at others is more explosive and able to open up to full stride without issue. One minute he can track a runner to the wire, and then the other, that same runner will leave him for dust. That's down to recovery not outright athleticism. You will more often than not see that teens and even very young 20's players cannot compete over a full game of PL football, looking absolutely exhausted by around 75min; we're constantly seeing this with Garnacho and Hojlund, and you will see it for the vast majority of players in that age bracket dotted throughout the league. Youngsters who have an adult's capacity are the anomaly. All of it revolves around recovery and power per sprint or output capability - hard-running is easier the less times you do it; the PL makes demands of hard sprints over and over and that's trying to match power with full-grown men who are not only stronger most times, but have far more capacity to repeat those runs than the youngsters do. A very simple way for a good adult player to swat a good young player is to simply run them off the pitch with superior athleticism and capacity. The youngster, more often than not, will flag. What you need to check is how many repeat max output runs a teenager can make compared to a full-grown adult. You'll see massive diminished returns inside a half, especially if physical tussles are also involved, which also take a massive draw from the body. Kobbie is good and able for the first or second load, but if you can pile that 3rd, 4th or even 5th on him, you will see a massive decline in succession.
Further to the above, in phase recovery, the game still goes on, so that's where a grown man can further take advantage as the youngster will still be flagging and less able to complete basic duties. i.e. if Garnacho is matched on an explosive attacking run that takes a lot out of him, the opportune time to go at him is immediately after that, where he has not recovered and will struggle to track a runner going in the other direction. Simply run him off the pitch. Give him that time to recover, however, and he'll look like his usual self.
This is one of the follies of playing youngsters most times, but the greater the team, the more they can offset such things, by being in control of the game and also having clean contingencies that always cover for this issue i.e. a partner or teammates who are on the pulse and quickly back up the kid in question and afford them the extra time to recover, particularly by quick retrieval in defensive phases, but also by passing the ball elsewhere in attacking phases, allowing the youngster to reintegrate with the play further down the line (reducing their need to sprint again until absolutely necessary).
Bottom line is, it's not about raw speed, pace, power etc. which will fluctuate wildly for most youngsters in a single game of football if it's a hard game or opponent(s) who work them at a rate beyond their recovery capacity.
A better midfield set who can run and work in unison, collectively hunting the ball and tactically pressuring will immediately make someone like Mainoo look deceptively adult in terms of physical capacity because they'll better mask his current capacity, which is perfectly normal for a teenage midfielder in the chaos and power battles of the PL midfield. This was also why it was a travesty ten Hag did what he did at Newcastle with the kid; two of the most physically powerful and athletic midfielders in the league, who grown men struggle against in direct tussles, and Mainoo against both until he came off the pitch! Not enough is spoken about how epic it was he could even perform in those conditions, let alone still look the part whilst being set up to fail.
