Mikel Arteta said Thomas Partey has 'come a long way' since he signed for the club after the Ghana international produced a starring performance in Arsenal's 2-0 win over Leicester.
Partey and Alexandre Lacazette were on target as the Gunners reclaimed fourth spot in the Premier League from Manchester United, who beat Tottenham on Saturday.
Partey put Arsenal ahead with an 11th-minute header while he also hit the woodwork with a shot and played a key role in the incident which led to the second-half penalty from which Lacazette scored to seal all three points.
