Emery: Chelsea are progressing under 'amazing' Potter

Potter succeeded Tuchel in the Chelsea dugout in early September, but his future was called into question following a run one win in 11 games to begin the year.

However, the former Brighton and Hove Albion boss has slowly turned things around, with Chelsea entering the international break on a run of three wins and a draw.

Villa boss Emery, who lasted 18 months at Arsenal before being sacked in November 2019, believes Potter fully deserves his chance to shine at a big club.

"He did amazing at Brighton and needs time to adapt his ideas at Chelsea," Emery said at Thursday's pre-match press conference. "Progressively, they're doing better and better.

"Tuchel's work was also amazing, but what Potter did with Brighton was really amazing and he deserved to take a step up with a team like Chelsea.

"They're now progressing. Everything he previously did with Brighton he can do as well with Chelsea. He just needs time.

"They have played well in the Champions League but have not been as consistent in the Premier League.

"But we know on Saturday we're playing one of the best teams in the Premier League. It's a good challenge for us and this is why I'm in the Premier League."

Villa have taken 10 points from their past 12 available, leaving them level on points with 10th-placed opponents Chelsea, and Emery is now targeting a top-half finish.

"When I arrived we were struggling at the bottom but the first reaction from the club, supporters, players, was amazing," Emery said. "Now we have escaped the bottom positions.

"Now we can think of our new challenge, which is to be in the top 10. This will start this Saturday. We think we have a good possibility to be there.
