West Ham United are close to finalising a €40m deal for Eintracht Frankfurt forward Sebastien Haller.
The Hammers have been linked with a number of strikers this summer, with Manuel Pellegrini eager to replace Lucas Perez, Andy Carroll and Marko Arnautovic - all of whom have left the club this summer.
Their search has led them to Haller, and L'Equipe state that their €40m move for the Frenchman has taken a step closer after they finally managed to convince him that joining the Hammers would be a good career move for him.
While the club do retain concerns of his ability to lead a front line on his own - he was part of a prolific front pairing with new Real Madrid striker Luka Jovic last season - the interest from West Ham is genuine. Their bid has been accepted and they will now discuss personal terms with the player, who was initially reluctant to join in hope he could move to a Champions League club.
A number of Premier League teams have looked at the player over the last few months, though have shared similar concerns over the player's ability without Jovic. The Hammers though appear ready to take their chance - he did manage to rack up 20 goals and 12 assists last season after all.
They turned to Haller after deals for Bournemouth's Callum Wilson and Celta Vigo's Maxi Gomez both became unlikely - Gomez has chosen Valencia and Wilson has been offered a new £100,000-a-week deal by the Cherries - he'd also be incredibly expensive, making a deal tough.
Atletico would also be open to parting ways with the 30-year-old permanently, but they fear that no European side will be able to meet their demands. As such, they are waiting to see if Costa generates any interest from Chinese Super League sides, given he came close to joining
During his four years with Chelsea, Costa managed to rack up 52 goals in 89 Premier League appearances, and he boasts the kind of proven track record which Pellegrini is keen on.
