The 21-year-old has scored four goals and assisted the same amount of goals during his 13 appearances, and that has sparked the question on whether or not he should be recalled to East London.
“I think that Grady is doing what we wanted for him, same as Josh Cullen,” he said in his pre-match press conference for the Burnley clash.
“He’s a player without any doubt will be part of West Ham in the future.
“I trust a lot in Grady and I think it was better for him to go and play 40 games this season and be ready for next season than to play here just some games. I think he must finish his season where he is.”
The 21-year-old has been a massive threat for the Baggies, averaging 1.8 key passes as well as 1.5 shots on goal per game according to WhoScored – proving that he can not only set up numerous chances but also stick them away himself.
With West Ham’s recent struggles in the final third, it appears strange that Pellegrini would not be tempted into bringing back Diangana back to London for the second half of the season.
Pellegrini has surely put the latest Sky Sports report in the bin with his update on the youngster, who now looks set to remain in the Midlands – much to the delight of many West Brom fans and their quest for Premier League football.
