Chelsea goalkeeper Petr Cech is convinced the Premier League title race is wide open next season.
Cech is looking forward to working with Jose Mourinho again.
He told the Daily Mail: "(Manchester) City have the same squad, Carlos Tevez apart, and they will bring players in to make the team as strong as possible. They have a great, experienced manager.
"David Moyes is experienced and he will find a great team, so if he wants to add players he will. I still see those two as the main threat.
"Arsenal are now under pressure. The manager is under pressure as everyone keeps reminding him of all the time since he won a title. They will want to show that they are there to challenge. It will be Chelsea and those three teams. Tottenham will be there, and Liverpool will want to improve."
