Concerns over Gianluca Scamacca's knee injury have been increasing over the last week, with many fearing he could be out for up to a month after he missed training ahead of the crucial clash with Everton at the weekend.
According to transfer expert Fabrizio Romano, West Ham have moved swiftly to plug the hole left by the Italian and have already reached an agreement to sign Danny Ings from Aston Villa for around £15million with adds-on.
Personal terms and a medicial could go through as soon as Thursday afternoon to make sure the striker is registered in time for the match with Everton on Saturday which has been dubbed 'El Sackico', as many are expecting West Ham manager David Moyes or Everton boss Frank Lampard to get the bullet if they fail to take all three points.
Many are now speculating that Sean Dyche, who managed Ings at Burnley, is being lined up to take the reins at West Ham should David Moyes get the sack.
However, he remains at 6/1 with the bookies to be the next West Ham manager, with Rafa Benitez still odds-on favourite to take the job.
Meanwhile, fellow striker Michail Antonio could be on his way out. The striker has been woefully out of form in recent games and looked disinterested in another poor performance in the 1-0 defeat to Wolves last week.
West Ham's all-time Premier League top scorer has been linked with moves away from the capital as Wolves, Everton and Crystal Palace have all been circling.
Antonio recently said on his own podcast: "If [West Ham] don't want me or Gianlucca [Scamacca], they are going to try get someone out or they might want to have three options.
"You have to deal with whatever comes your way and that's how I stand with it. I want to play football, and that's all I care about."
