The Hammers have been busy in the transfer market this summer, as they have now landed Lukasz Fabianski, Ryan Fredericks, Issa Diop, Fabian Balbuena, Jack Wilshere and Andriy Yarmolenko, with Felipe Anderson also inbound.
However, the spending isn't stopping there, and another centre back is believed to be on Manuel Pellegrini's wish list, despite already landing Diop and Balbuena to boost his options.
Now, the Daily Mail report that West Ham have offered a huge £18million deal for Lyon defender Marcelo, but the French club have rejected it, demanding more than £20million for his services.
Lyon paid just £6million to land Marcelo from Besiktas last summer, and West Ham offering £12million profit for a 31-year-old should have been enticing, but Lyon have allegedly said no.
Marcelo will be 32 by the end of the 2018-19 season, and West Ham must seriously think whether paying more than £20million for the 6ft 3in defender is really smart business, even if Pellegrini wants him.
The Brazilian has had spells with Wisla Krakow, PSV Eindhoven, Hannover, Besiktas and now Lyon since leaving Santos in 2008, and has yet to be capped by Brazil at international level.
It remains to be seen whether West Ham return with a new bid for Marcelo, but fans must be left wondering whether the Hammers are in danger of spending huge money on a player approaching the final years of his time as a top defender.
