Chelsea boss Jose Mourinho says Arsenal and Manchester United will provide greater competition for his defending Premiership champions than Liverpool.
Mourinho is impressed by Arsenal and Man Utd's signings
Mourinho's captain John Terry has tipped the Reds to run Chelsea close as they go for a third successive title.
But the manager said: "I still believe United and Arsenal will be the biggest threat. They will be the better teams.
"I say that because of the quality of their football, the way they play, the improvements in their squads."
Liverpool boss Rafael Benitez has bolstered his attack with the arrivals of Craig Bellamy and Jermain Pennant, but Mourinho remains unconvinced.
"Liverpool are different. They are very competitive, it's very difficult to beat them," he said.
"If they score a goal before you score it's very difficult to change it because they defend really well with 11 players very, very compact.
"They are tactically very good and they are potentially fighting for the front pack but I still fancy more the way Manchester United and Arsenal play football."
Mourinho is impressed by the summer purchases of both Arsenal and United.
"United will improve a lot by having Michael Carrick. He's a very, very good player and he will improve them," said the Chelsea boss, currrently in the US with his team on a pre-season tour.
"Arsenal have a very good group of players, and some young players with great motivation.
"Tomas Rosicky is also a very important player for them and can bring them the kind of quality - I don't want to compare him to Dennis Bergkamp because he was more than special - but Rosicky can bring that kind of quality to the left side."
