William Saliba has hailed the impact of new first-team coach Gabriel Heinze, as the former Manchester United defender is the mastermind behind Arsenal's defensive dominance under Mikel Arteta. Heinze, who joined Mikel Arteta’s staff in July, has quickly become a driving force behind a Gunners side that have conceded just seven goals in 14 Premier League matches; the best defensive record in the division.

Mikel Arteta has confirmed that William Saliba and Leandro Trossard are major doubts for a London derby meeting with Brentford on Wednesday night. Both players missed the Gunners' 1-1 draw with Chelsea at the weekend. Arteta also delivered updates on Kai Havertz and Gabriel Magalhaes as they remain in the treatment room with more serious knocks.

William Saliba will not play for Arsenal against Chelsea in a top of the table clash on Sunday afternoon. The defender picked up a knock in training and will not be fit enough to play for the Gunners at Stamford Bridge. With Gabriel also out injured, Mikel Arteta has entrusted Pierro Hincapie and Christhian Mosquera as his centre-half pairing for the London derby.

William Saliba could not resist taking aim at Tottenham star Richarlison following Arsenal's thumping 4-1 win over Spurs in the north London derby on Sunday. Eberechi Eze scored a hat-trick as Mikel Arteta's side claimed the bragging rights and moved six points clear at the top of the Premier League table. Saliba celebrated the victory on social media after the game, with Declan Rice quick to join in.

Arsenal have been dealt with a fresh injury blow with star players William Saliba and Gabriel Martinelli ruled out of action for their upcoming game with Brighton & Hove Albion in the Carabao Cup. The duo, along with Bukayo Saka, Declan Rice and Riccardo Calafiori, picked up problems in their last Premier League encounter against Crystal Palace, which the Gunners won 1-0 to extend their lead at the top of the Premier League table.
