Olympique Marseille's Michy Batshuayi celebrates after scoring against Lorient
Chelsea have struck an agreement with Marseille for the signature of Michy Batshauyi according to French newspaper L'Equipe.
The Belgian international had been an option for both Tottenham Hotspur and West Ham, but now looks destined to move to Stamford Bridge.
In snapping up the former Standard Liege man, Chelsea have increased the pressure on the supremos at their fellow London clubs, to get it right in the transfer market.
Tottenham Hotspur chairman Daniel Levy
Chairman Daniel Levy is a tough negotiator but appears to have been priced out of the market for the Belgian.
This is fine, considering Spurs have other options, but these are not straightforward. Top target Vincent Janssen has emerged as an option for French champions PSG, report RMC, while Gianluca di Marzio reports Real Betis have entered the race to sign Antonio Sanabria.
Tottenham may still fancy their chances of signing either, but Chelsea's signing of Batshuayi reduces the margin of error for Spurs in relation to their subsequent options.
West Ham co chairmen David Sullivan and David Gold before the match
West Ham fans meanwhile are growing increasingly impatient at the results of co-chairmen David Gold and David Sullivan when it comes to signing a striker this summer.
Batshuayi had been seen as a credible option, while they big larger amounts for the potentially unattainable Alexandre Lacazette.
Carlos Bacca of AC Milan is one alternative they could now consider, while they may be left to consider Liverpool flop Christian Benteke.
Chelsea's Batshuayi deal will be a disappointment to both clubs and while a short term blow, there is plenty of time for them to get in their own top quality players, but the pressure has been increased on them to do so.
