Luton are haggling with Inter Miami for Josef Martinez.
The Sun says Inter are demanding £10m to sell the 30 year-old Venezuela international.
Luton have bid for Martinez, but their offer has fallen short of his asking price.
And it's suggested they need Martinez to push to leave at his end to get a deal over the line.
Martinez, meanwhile, has hit it off with Leo Messi since the Argentine arrived in the MLS last week.
