Mikel Arteta has explained why he chose to substitute Leandro Trossard during Arsenal’s last-gasp defeat by Aston Villa.
The Belgian winger returned to the Gunners’ matchday squad in the Premier League on Saturday lunchtime after missing the draw with Chelsea and midweek win over Brentford due to a calf injury that forced him off in the statement Champions League defeat of Bayern Munich on November 26.
