Chelsea manager Xabi Alonso admitted Arsenal are difficult to beat after his side surrendered an early lead to lose 2-1 to the Premier League champions at the Emirates Stadium on Sunday.

Chelsea made a flying start when Morgan Rogers stunned the home crowd with a right-footed volley after just 77 seconds, but Arsenal responded to turn the game around and maintain their perfect start to the season.

Kai Havertz restored parity for Arsenal in the 25th minute before captain Martin Ødegaard completed the comeback shortly after half-time.

Alonso acknowledged the difficulty of breaking down Mikel Arteta’s side but felt Chelsea had enough opportunities to get more from the game.

“They are hard to beat, they are hard to create chances (against), but we had three or four chances to score more than one goal. This is a process. It’s still early days for us,” Alonso said.
