Former Chelsea ace Joe Cole was disappointed with Chelsea’s performance in the 1-0 defeat to Croatian side Dinamo Zagreb.

According to Joe Cole, the performance was very poor, and the players who came into the team did very poorly.

Joe Cole claimed Kalidou Koulibaly and Hakim Ziyech were the worst performers in Croatia.

Asked to assess Chelsea’s performance in Croatia, Cole told BT Sport: “Where do you start? The guys at the back have got to pull it together as soon as possible.

“People will look at the goal but we could have pulled out countless examples when Koulibaly was the wrong side of his man. For a 31-year-old defender, he needs to get up to speed quickly.

“At the other end of the pitch, is there a lack of confidence? The only positive for Thomas Tuchel is there were a lot of players knocking on his door asking why they’re not play and saying they want a chance.

“Those players have come in and haven’t taken their chance so at least he can tell them now why they’re not playing.

“Ziyech, he’s got a lot of talent but for one reason or another it’s not clicking for him at Chelsea.

“He wasn’t at his best and he hasn’t been at his best. He’s trying hard and trying to make things happen but it’s not clicking.

“It’s a bad night for the club. It’s a massive shock.”
