Samir Nasri has told Arsenal they must lean to win ugly after a week which saw the club's Champions League and FA Cup hopes wrecked.
A 4-0 defeat at AC Milan saw their European hopes dashed, and came just days after Sunderland had all but ended the Gunners' hopes of claiming a trophy this term, losing 2-0 at the Stadium of Light.
Successive disappointments mirrored last season's problems, which saw the club's Carling Cup final defeat, FA Cup and Champions league exits preceded by the collapse of their Premier League title challenge.
And Nasri, who left the club in the summer for rivals Manchester City, believes lessons must be learned at the Emirates Stadium.
"Sometimes it's good to win ugly, you don't always have to play good football to win. Arsenal play good football but after seven years they don't win so that's difficult for them but they have a good philosophy. I know they'll find some solution," he noted.
The Frenchman's acrimonious exit from north London came after the club's sixth successive season without a trophy.
His exit was compounded by the departure of Gael Clichy and Cesc Fabregas, with many accusing Nasri of being money motivated after the refusal of a new contract under Arsene Wenger.
"I don't want Arsenal to fall down," Nasri said. "I want them to win the FA Cup or something because I have respect for the players and the manager.
"I know from the start that I made the right choice. We are top of the league, and still there in the Europa League. What Arsenal do doesn't matter."
Nasri has failed to adapt to his new role with City, starting only 15 league games for the Premier League pace-setters this term.
The 24-year-old has scored five goals this season, including against Tottenham Hotspur in a crucial top of the table clash in January, and Nasri has promised to improve in the twilight of the season.
"It's always tough when you change, when you go to another team and have to be involved 100%, and I wasn't.
"Now I start to be settled and you will see a better Samir every week. You have to work when you don't feel well and not producing what everyone expects.
"I was always confident about my quality and you will see that."
