Chelsea have been the best Premier League team in the past few months.
Thomas Tuchel was brought in January to replace struggling Frank Lampard after a heavy summer spending last year.
The German coach got the best out of the Chelsea squad and helped the team reach the FA Cup and Champions League finals in his maiden season.
Chelsea will be hosting the Gunners in their next Premier League game at Stamford Bridge.
Mikel Arteta credits Tuchel for the outstanding transformation he has done at Chelsea.
The Gunners managed to secure a 3-1 victory over the Blues earlier last season.
“Well, probably they’ve been the best team in the league in the last few months,” said Arteta.
“What Thomas has been able to do since he arrived has been exceptional.
“He put the team in two finals, the way the team is looking, how solid they’ve been defensively as well, how composed and regular they have been in their performance has been excellent.”
