Chelsea manager Maurizio Sarri believes Manchester City remain the team to beat in Europe ahead of their Premier League trip to the Etihad Stadium on Sunday.

Sarri's Chelsea were the first side to defeat City in the league this season when they claimed a 2-0 win over the champions at Stamford Bridge in December.

Sarri says at the moment he does not consider Chelsea can win the league. He says we are fighting for the top four. He adds that he thinks Man City are currently the best team in Europe. #MCICHE

City suffered two more losses over Christmas but have now returned to the top of the league table, ahead of Liverpool on goal difference.

"At the moment, in my opinion, Manchester City is the best team in Europe," Sarri told reporters on Friday.

"(Pep) Guardiola is in the third season in the Premier League. We have to try to reduce the gap."

City coach Guardiola counted fourth-placed Chelsea among the title contenders this week but Sarri dismissed his team's chances by calling it a two-horse race.

Sarri says in the home match against Man City we were lucky in the first half beause we scored at a difficult moment. We defended well and deserved to win in the second half. #MCICHE

"At the moment, I don't think (we can win the title)," said Sarri. "We will be able to fight for the top four in this season. No more, I think.

"We can win something, of course, but in the Premier League there is a fight between Liverpool and Manchester City."

Sarri was pleased with January signing Gonzalo Higuain's instant impact at Stamford Bridge, scoring two goals in a 5-0 thrashing of Huddersfield Town last weekend.

The Italian coach expects the Argentina striker to build an on-pitch relationship with playmaker Eden Hazard, whose future at Chelsea remains uncertain amid interest from Real Madrid.

Sarri says he speaks every day with Hazard but about his position on the pitch, not about his future. Sarri will be very pleased to see him stay but he wants him to be happy and it is up to him. #MCICHE

"I think Gonzalo is a great player," Sarri added. "He did very well everywhere. In Madrid, in Naples, in Milan. Maybe not very well in Milan, but he's a great player and I think he's very useful for Eden.

"They are really very suitable to play together, I think. It's very important for us he's determined. I think the impact with other players will really be very good for us."
