Jose Mourinho believes Arsenal can emulate the success of their famous 'Invincibles' side - but only if they sign four top-class players.
The Chelsea manager guided his team to a goalless draw away to the Gunners on Sunday - effectively securing the title in the process - and says Arsene Wenger needs to invest if he wants his side to challenge for the league next season.
“At this moment, it’s very difficult in the Premier League for a team to be dominant,” said Mourinho.
“This is not Germany with Bayern (Munich). This is not Switzerland with Basel. This is not Scotland with Celtic.
“Arsenal have a phenomenal squad. Thierry Henry said they need four top-class players. Give Arsenal four top-class players and I think they will again be the Invincibles."

Chelsea have faced relatively little competition in the Premier League over the course of the current campaign, but Mourinho is certain the Blues' rivals will invest heavily over the summer.
“Man United have a phenomenal squad, including the most expensive player in the history of the Premier League (Angel di Maria), who is not playing.
“They are a club where Financial Fair Play doesn’t make a huge difference for them and they will invest hugely again in the summer.
“Man City have done phenomenally, winning two titles in three years, and people say they will invest hugely.
“Liverpool fighting for the title for many years. So next year it will be even more difficult for everyone than this year.”
