Arsenal boss Arsene Wenger feels Everton are among the title contenders.
Wenger believes the tight nature of the Premier League means it is far too early to talk about possible title challenges.
"In England you have so many teams who can win the league, nobody can guarantee they will do it before the season starts," he said. "We have Man United, Liverpool, Arsenal, Chelsea, Man City and Tottenham who want to win it.
"Everton now look to be a contender, too. So it is impossible to say mathematically we will win it."
