Confirmed squad news, expected line-up, Premier League injury latest today
The winger joined the Gunners from Brighton on Friday in a deal that could be worth up to £26 million.
Arsenal believe they submitted the paperwork Friday afternoon meaning Trossard could be involved against United at the Emirates Stadium.
“I’m very excited to start,” Trossard said in his first interview with Arsenal.com. “It’s a big club and I’m ready to show the fans what I can do.
“Everyone has already seen how well we are doing and I am here to help make their dreams come true – myself included.”
The Gunners are expected to choose the same starting line-up that beat Tottenham 2-0 in the North London derby ahead of Sunday’s game with United.
Gabriel Jesus is still out with a knee injury and Reiss Nelson has a hamstring injury, but everyone is ready for manager Mikel Arteta.
Predicted Arsenal XI (4-3-3): Ramsdale; White, Saliba, Gabriel, Zinchenko; Odegaard, Partey, Xhaka; Saka, Nketiah, Martinelli.
