Frank McAvennie has suggested that Grady Diangana’s move to West Brom could come back to “haunt” West Ham this season.

Speaking exclusively to Football Insider correspondent Dylan Childs, the former Hammers striker suggested that the winger will be eager to “prove something” to his former club when the two sides meet in the Premier League later in the campaign.

The Baggies confirmed the 22-year-old’s arrival from the Irons last week in a deal worth £18 million including add-ons, as Football Insider understands.

And McAvennie has suggested that Diangana’s transfer leaves West Ham with a lot to ponder.

Speaking to Football Insider, he said: “There is a big question mark when it comes to West Brom.

“They’ve got Slaven Bilic, Julian Dicks and now they’ve got Grady Diangana. People always want to come back and haunt their old clubs.

“The young boy Diangana will come back and want to play and show what he can do.

“I thought Slav was doing alright. If he was still in charge I think we would have been doing better than we have been in the last couple of years. He will want to prove something.”

Diangana’s departure led to widespread uproar from some quarters in east London, including a social media outburst from Hammers captain Mark Noble.

As for the wide man, he impressed hugely during a loan spell with Albion last season, registering eight goals and seven assists in 30 Championship outings.
