What did he improve. He looks the same to me.
His improvement is mostly in the defensive department, which probably has to do with the way we play this season and his new position.
Comparisons can be made between this year so far (15 matches/13 starts) and his last season here (15 matches/13 starts).
Offensively he didn't really improve:
0G/1A in 2023 --- 1G/1A in 2022
27 passes (80% succ. passes) in 2023 --- 25 passes (81% succ. passes) in 2022
0.3 crosses in 2023 --- 0.3 in 2022
0.9 created chances in 2023 --- 0.5 in 2022
But defensively he's doing better:
1.9 tackles in 2023 --- 0.9 in 2022
0.9 interceptions in 2023 --- 0.7 in 2022
1.9 clearances in 2023 --- 0.9 in 2022
1.4 aerials won in 2023 --- 0.8 in 2022
