Martinez collided with Jarrad Branthwaite as the pair challenged for a cross and after more than eight minutes of treatment, the Argentina international was carried off on a stretcher to a waiting ambulance.

The Argentina goalkeeper later posted a photo of himself in a hospital bed on Instagram, writing: “Thank you for all the messages, the operation went well.”

He added: “We’ll be back in a few weeks.”

Martinez had earlier played his part in Chelsea’s 2-0 win that also earned his side their first Premier League clean sheet in nine months.

Speaking immediately after the match, Chelsea boss Xabi Alonso said that Martinez had been taken to hospital for “precautionary tests”.
