Arsenal legend and former goalkeeper David Seaman believes the club's latest acquisition can be the key to their title challenge next year.

Petr Cech completed a £10million move to the Emirates Stadium on a four-year deal on Monday and ex-Gunners ace Seaman feels the capture could guide Arsene Wenger's side towards a first premiership since 2004.

"Chelsea's loss could, and likely will, be Arsenal's gain," Seaman told social website BreatheSport.

"In my opinion this signing could genuinely be the difference between who will come first and who will come second next season."
