West Ham have offered a mammoth £81million to seal the signing of Sebastien Haller from Eintracht Frankfurt, Football Insider can reveal.

The Premier League club are putting the finishing touches to the deal and are hopeful negotiations can be finalised later today.

This means the total cost of the deal is at least £81million, although the transfer fee as well as the wages will be spread across many years.

Haller flew into London for a medical yesterday and to finalise personal terms, and a deal that would be regarded as a major coup could be announced within the next 24 hours.

It would represent the highest fee West Ham have ever paid for a player and comfortably trump the price of £36million plus add-ons paid to Lazio for Felipe Anderson last year.

The Hammers have pulled out all the stops to land Haller after failing in pursuits of Maxi Gomez, Salomon Rondon and Callum Wilson.

His salary package will instantly lift him into the top bracket of earners at West Ham alongside Javier Hernandez, who joined two years ago, also after scoring prolifically in the Bundesliga.

Haller scored 15 goals with nine assists in just 23 starts for Frankfurt in the league last season and his overall tally of 33 goals in 77 appearances for the club is an impressive one.
