It's claimed that the Hammers are entering the race with a permanent offer, where as Napoli want to take him on loan for the rest of the season with a view to a €20million (£17million), with an extra £1.7million in bonuses.
Celta want around €27million (£23million), and with West Ham's offer 'on the rise', they may just manage to pip Napoli to the midfielder's signature.
A permanent deal is more appealing than a loan for Celta, so the Hammers may have a great chance to pull off a real coup.
Lobotka, 25, has starred for Celta since joining from Danish side Nordsjaelland in 2017, earning comparisons to Luka Modric with his style of play.
A diminutive, technically-gifted midfielder, Lobotka could provide real quality to the West Ham midfield, giving Mark Noble and Declan Rice some much-needed help.
This isn't the first time West Ham have been linked with Lobotka; Gianluca Di Marzio reported over the summer that West Ham wanted Lobotka and teammate Maxi Gomez, but The Guardian suggested that they had given up hope of a deal because they thought he was going elsewhere.
Now, West Ham could finally land their man, and beating Napoli to his signature would be a real statement of intent under returning boss David Moyes.
