Arsenal manager, Mikel Arteta, has received a triple injury boost as they prepare to play Bayer Leverkusen in the first leg of the Champions League last-16 tie.

The trio of William Saliba, Leandro Trossard and Riccardo Calafiori were spotted in training on Tuesday morning.

Saliba has been unavailable for the Gunners’ last two fixtures against Brighton and Mansfield Town.

The French defender sustained an ankle injury during their 2-1 win over Chelsea.

The duo of Calafiori and Trossard limped off during the 2-1 victory at Mansfield in the FA Cup fifth round.

However, captain Martin Odegaard and defender Ben White, were not spotted with the squad.
