Former Arsenal goalkeeper David Seaman has suggested that Petr Cech's move to the Emirates could end up affecting who wins the Premier League title next season.
The 33-year-old completed a move to the Gunners on Monday for a fee thought to be in the region of £11m.
Cech called an end to his 11-year spell at Stamford Bridge after playing second fiddle to Thibaut Courtois last season.
After the transfer was announced, Seaman told BreatheSport: "Chelsea's loss could, and likely will, be Arsenal's gain. In my opinion, this signing could genuinely be the difference between who will come first and who will come second next season."
Reports have claimed that Cech has signed a four-year deal with Arsenal.
