Flamini returns, Poldi sidelined

French midfielder Mathieu Flamini has returned to Arsenal after being released by AC Milan, the Premier League club announced on Thursday.
The 29-year-old central midfielder made 153 appearances for Arsenal between 2004 and 2008 before leaving for Milan, where he spent five seasons.
He has been training with the Arsenal squad for the past month and Arsenal manager Arsene Wenger said he was delighted to have Flamini back on board.
"We are very pleased Mathieu has agreed to rejoin us," Wenger told the Arsenal website, www.arsenal.com.
"He is a player of real quality, with a fantastic work rate and great mentality.
"As we know, Mathieu is a strong midfielder, but is also comfortable playing in defence too. He is a very good addition to our squad."
Wenger also revealed on Thursday that the club will be without Lukas Podolski for up to 10 weeks after the German forward damaged his hamstring in Tuesday's 2-0 win over Fenerbahce.
