Barcelona great Hristo Stoichkov has been unimpressed by Antoine Griezmann this season.

Stoichkov insists former Barca teammate Ronald Koeman has been let down by the France attacker.

"Now everyone says 'Koeman, it's Koeman', but it's not all his fault," Stoichkov says.

"It is the eleven (players) who play, and in Barcelona it is not about how to play against such teams (middle teams).

"He (Griezmann) has not scored against Liverpool, Juventus, PSG, Real Madrid or Atletico, and he cost a lot of money..."

Griezmann has scored twelve goals in 35 appearances for La Liga this season.

Stoichkov played 255 games for Barcelona and scored 117 goals during his time at the club.
