David Seaman talks about Petr Cech in BBC interview

On the impact of Cech:

He's part of the jigsaw that's nearly finished. It's not all about Cech. We still need a good centre-half and a Patrick Viera or Yaya Toure-like midfielder. But before, we were having to sell players - like Cesc Fabregas and Gael Clichy. The club's now got stability and the finances to pay wages and big transfer fees. By bringing quality players in like Cech, that will be what we need to win the Premier League.

On Cech arriving as first choice keeper:

He won't want to come to Arsenal to be a number two. He's got trophies behind him and I would say he's bang in the prime of his career. He's got at least another five or six years ahead of him.

On Cech being missed at Chelsea:

I'm sure he will be. He's a character. He's a confident speaker and when you see him out in public, he loves talking about goalkeeping. It's a massive boost for Arsenal. It's what they needed. He must have had a list as long as his arm of clubs to go to, so I'm so happy he chose Arsenal.
