Republic of Ireland goalkeeper Darren Randolph has finally completed his move back to West Ham United.

His transfer from Championship outfit Middlesbrough had been delayed over concerns about a thigh injury, but it has now been completed. He's penned a three-and-a-half-year contract.

Randolph left the Hammers in 2017 and returns for an undisclosed fee as cover for Lukasz Fabianski, who is currently sidelined due to inflammation of the scar tissue in his hip following surgery.

"I'm delighted to be back at West Ham. I had no hesitation in coming back. West Ham is a massive club, with fantastic supporters and an excellent squad of players," Randolph told the club website.

"This opportunity was simply too good to turn down, though. It's a great feeling to be back in the Premier League with such a fantastic club, and I can't wait to get started."

The transfer was completed this morning following reports last week that the move was put on hold after issues arose during Randolph's medical.

West Ham wanted to be sure he would not break down once he joined, having recently had a thigh injury. But Randolph is fit again and, with Fabianski out until next month, he could go straight into the team ahead of David Martin when the Hammers host Everton in the Premier League on Saturday.

"It's a great challenge for me and I am really looking forward to working with the goalkeepers here and helping the team in any way I can," added the 32-year-old Bray man.

"I'd like to thank everyone at Middlesbrough - the management, staff, players and fans - for their support. I had a great time there and wish them all the very best for the rest of the season."
