Liverpool manager Jurgen Klopp believes six teams are capable of winning the Premier League title this season.
Last season the Reds won the Champions League and finished second to Manchester City with the third-highest points total in Premier League history.
"I'd say there are at least six teams in contention," he told Sky Sports.
"Everton, for example, have tried to stay very ambitious. They have done a lot and I think there are still maybe a couple of players to come in. They had a good team last year and they have improved, with very interesting signings.
"I don't know where people get the idea that Arsenal will not challenge, that Chelsea will not challenge with Frank [Lampard] bringing complete excitement to the club.
"Okay, they cannot really be busy in the transfer window, but after years when all the young boys were on loan, now they finally bring them back and get the benefit of that.
"It's like it's made for a transfer ban. Now [Tammy] Abraham and all these other guys come back and it's a fantastic team."
