Petr Cech believes Arsenal's strength in depth means they are better equipped than ever to win the Premier League since he has been at the club.
The goalkeeper, who arrived at the Emirates from Chelsea in June 2015, believes the Gunners struggled last season due to a lack of options at the disposal of Arsene Wenger.
'I think the first (quality) is the strength in depth,' Cech said. 'When we were unlucky with long-term injuries last season, we had to use the same players in so many games and you lack energy in certain parts of the season.
