Arsenal expect to have skipper Granit Xhaka available for Saturday’s crunch clash against Liverpool.
The Switzerland international missed Saturday’s win over Burnley with a back injury, but boss Unai Emery hopes to have his key midfielder available for the trip to Anfield.
Xhaka has resumed first-team training this week and barring any complications should travel with his team-mates to Merseyside.
Mesut Ozil is also closing in on his first-team return after missing the first two games of the season.
The highly-publicised security threat to Ozil and Kolasinac prevented the pair from travelling to Newcastle for the opening day win, while the former also missed the win over Burnley – though the official line was he was lacking match fitness.
But Ozil has trained as normal this week and is set to be considered for the game against Jurgen Klopp’s side.
Liverpool and Arsenal are the only two teams in the Premier League who have a 100 per cent record.
