West Ham United youngster Josh Cullen has penned a long-term contract with the club until 2018.
The midfielder, 19, made his Premier League debut for the Hammers during Saturday's 3-0 win over Liverpool at Anfield.
"I'm delighted to get the deal done and extend my time at West Ham. I'm over the moon to get another couple of years and I'm looking forward to the club moving forward and hopefully progressing to the first team," he told West Ham's official website.
