Thomas Partey was outstanding for Arsenal in their narrow 1-0 win over city-rivals Chelsea in the English Premier League on Sunday afternoon.
The Ghanaian international dominated proceedings in the middle of park to help the Gunners secure a crucial victory at the Stamford Bridge.
Gabriel’s solitary strike in the 64th minute was the difference between the sides.
The win sees Mikel Arteta’s side return to the top of the Premier League table with 34 points after 13 matches.
Meanwhile, the Blues’ 12-match unbeaten home run in all competitions since losing to the Gunners in April comes to an end, and they stay seventh.
