Chelsea fans fuming with 'disgraceful' pitch as Christopher Nkunku hobbles off injured in US friendly

Chelsea have been dealt a major blow with Christopher Nkunku hobbling off injured during a preseason friendly.

The Blues were taking on German giants Borussia Dortmund in their tour of the United States when new signing Nkunku landed awkwardly on his knee.

Mauricio Pochettino and his coaching staff collectively held their breath as the big-money recruit received treatment on the pitch.

But unfortunately for Chelsea fans, he was unable to continue and was ultimately substituted off.

Depending on how serious the injury is, it could be a big blow to Chelsea's rebuild as they push to redeem themselves after last season's blushes.

But while the severity of the incident is yet to be confirmed, Blues fans are posting their fingers at the pitch.

Just at the glance, Soldier Field in Chicago doesn't look like it boasts a particularly pleasant plying surface with the ball bobbling around all over the place.

Now fans have flocked to social media to vent their frustrations, many of whom calling the pitch 'disgraceful' and directly blaming it for Nkunku's injury.

One fan described it as: "A war zone of a pitch."

While another added: "I'm still blaming the pitch, it's shambolic."

As one Chelsea fan page tweeted: "This pitch is an actual disgrace. How are we going to lose Nkunku to injury already and it’s only been 20 minutes?"

Nkunku arrives in west London with big expectations after finishing top scorer of the Bundesliga last season.

But the Premier League season hasn't even started yet and the Blues are already low on attacking firepower, it seems.
