Cristiano Ronaldo's homecoming to Manchester United has grabbed all the headlines, but William Gallas believes his old team, Chelsea, are stronger than the Red Devils, especially with the addition of Romelu Lukaku.

Speaking to Genting Casino, William Gallas was full of praise for Chelsea and Romelu Lukaku:

"They are the champions of Europe. They look stronger and stronger. If they are really focused they can beat any records, especially now they have Lukaku."

This is a scary team for any opponent to play. Manchester United fans may think they have a stronger team with Ronaldo back, but if you take every player position by position then I believe Chelsea is stronger than [Manchester] United."

I really can’t see any club that can beat them. Tuchel is a perfectionist and he always has a tactical plan. Whenever he plays against the league’s best managers, he always finds the solution. Chelsea can win the Premier League, definitely."

Chelsea have started the season in great form and are currently joint top of the Premier League table with Liverpool. Manchester United, on the other hand, have had some mixed results.

While they are still unbeaten in the Premier League, they suffered a defeat against Young Boys in the UEFA Champions League and crashed out against West Ham in the Carabao League Cup.

Manchester United fans, however, will be buoyed by the immediate impact Cristiano Ronaldo has had at the club so far. The 5-time Ballon d'Or winner has hit the ground running and looks determined to guide the club to trophies this season.
