Chelsea great Frank Lampard believes the signing of goalkeeper Petr Cech can propel Arsenal towards the Premier League title this season.

Arsenal signed the Czech Republic international on a four-year deal from Chelsea recently and many, including former teammate Lampard, believe it is a major coup for the Gunners.

"Arsenal signing Petr Cech is a big deal," Lampard said.

"A lot of mates who are Arsenal fans have bemoaned their keeper situation for ages.

"Cech is a world-class keeper and person and can help push Arsenal into the running next season.

"Arsenal weren't a million miles away over the last few seasons.

"They are always challenging before falling just short but Cech going there, as John Terry said recently, will save them points.

"Manchester City and Chelsea will be challenging for the title once again.

"They remain favourites but Petr will make a difference."
