Bradley-West, who plays Samwell Tarly, and Dempsey, who stars as Gendry, turned up at the Red Devils’ UCLA camp to watch Jose Mourinho’s latest session.

The pair received a warm welcome from the Portuguese boss and his squad as they eagerly watched the team being put through their paces on a sunny day on the west coast of the United States.

And the duo were also given the chance to get their hands on the Europa League trophy, which Manchester United clinched at the end of their last campaign.

Game of Thrones, which was first broadcast in 2011, returns this evening for its seventh series.

Northern Irish comedian Patrick Kielty also dropped in on the session - and brought his starstruck young nephew along with him.

Mourinho’s team face Real Salt Lake in their next pre-season match tomorrow, after beating LA Galaxy 5-2 in the opening match of their tour yesterday.
