Chelsea have suffered a setback ahead of the new Premier League season, with Hakim Ziyech having to be substituted with what appeared to be a dislocated shoulder.

Ziyech had put Chelsea ahead against Villarreal in the UEFA Super Cup at Windsor Park, but then suffered much frustration after he was caught by Juan Foyth.

The former Tottenham defender looked on bemused before concern took over as the pain soon became etched over his opponent’s face.

Ziyech was holding his right shoulder as medics raced onto the field as a lengthy absence ensued.

He appeared to be given some sort of inhaler to help with the pain as the Chelsea medical team took cautious care of him before he eventually left the field.

The Moroccan even had to use his Blues jersey as a sling as he hobbled from the field.

Some early speculation claimed it was a dislocated shoulder but that has yet to be confirmed.

American Christian Pulisic star came on to replace him for the final seconds of the opening period.
