The Brazil international sustained a knock to his knee against Liverpool last weekend and he was substituted before the 55th minute of the game.

This played a big part in the final result. Arsenal were leading 2-1, but ended up sharing the spoils after a late equaliser from Mohamed Salah .

Gabriel missed the subsequent game against Preston North End in the Carabao Cup, but he has returned in time to face the Magpies.

The centre-back was spotted with the travelling squad earlier today and he is expected to make the starting line-up for tomorrow's game.

Arsenal are already five points behind the league leaders Manchester City and the upcoming clash is a must-win for the London giants.

While Gabriel is back in contention, the Gunners will continue to be without captain Martin Odegaard while Ben White is doubtful.
