When I said he needs work on attack; I don't think his attack is limited due to technical reasons or raw related attributes, but more on knowing what to do in the attack phase. E.g. the long passes he received are often controlled first regardless the scenario, even when the situation allows him to knock the ball down and run on the first touch.
Also his way of taking on the opponents is pretty much sprint to byline and cross.
I never doubted his raw ability for attack, but his attack needs more work than defense cause of that.
His defense is actually pretty decent. He had quite some interception, hence the position. The 2 things if I want to be picky about his defense are: first, he leaves too much room between he and the dribbler, almost assuming they will do the same as him, try to dash pass him, so with his pace and the room he was pretty effective on preventing people get pass him or do a long pass/cross, but it makes the opponent pressure free on switching angle or hit a low pass.
The other thing about him is the commitment he has on the man after a switch up, or the realizing he became the marker that is responsible.
Otherwise, he is the only one on our team that you can leave him on the flank to defend without the CB supporting.
For his pace, it can be used for defense and offense.
