Grady Diangana has his heart set on staying at West Bromwich Albion for the season, rather than returning to West Ham United, as reported by Football Insider.

What's the story?

The 21-year-old has been excelling on loan at the Hawthorns, scoring 4 goals and assisting another 4 in 11 Championship starts and 3 substitute appearances.

He has impressed so much that there has been a debate about whether the Hammers should recall him during the winter window.

Manuel Pellegrini had initially ruled out the move, as he was quoted on West Ham's official channels as saying: "I trust a lot in Grady, and I thought that it was better for him to go and play 40 games this year, and be absolutely ready for next season, than play here just some of the games.

"I think that we must continue supporting him, we must continue being happy with his performances, and he must finish his season where he is."

Manuel Lanzini suffering from a fracture to his collarbone against Burnley appeared to reopen the door to a London Stadium return, though Diangana has seemingly closed it again.

Big call

This is a big call for Diangana to make, which shows plenty of decisiveness on his part.

If this has been relayed back to Pellegrini it will likely make up the West Ham manager's mind for him.

The 21-year-old is clearly comfortable playing for Slaven Bilic's side, which has come across in his performances, while it will be good experience for him to be fighting for promotion from the Championship, with West Brom currently top of the table.

Diangana would have been a useful option for the Hammers to have at their disposal for the second half of the campaign, but it is difficult to argue with the winger's thinking, as he would have Felipe Anderson for competition at London Stadium.

It seems as though West Ham fans will need to wait until next season to see the academy graduate in claret and blue again.
