Aston Villa coach Unai Emery's description sums up Chelsea's current situation 

Aston Villa manager Unai Emery has described Chelsea as a very good team coached by a good manager, Mauricio Pochettino. 

He, however, described the Blues as a club previously contending for the top seven in the Premier League.

“They’re a very good team with a very good coach," the Spaniard said ahead of Sunday's clash. 

"Previously, they were contenders to be in the top seven teams in the Premier League. It’s a tough match.”

Chelsea have endured a poor start to the season with just one win in five games.
