The Colombian ace would be a great addition to the West Ham United squad.
Manuel Pellegrini has already been extremely active during this summer's transfer window, bringing in Issa Diop for £22 million and Ryan Fredericks on a free transfer.
The Chilean's business is far from finished, however, with reported moves for Lazio's Felipe Anderson and Nice's Alassane Pléa still believed to be in the pipeline.
According to a report from the Birmingham Mail, Wolves and Tottenham are keen on signing the attacking midfielder this summer, after his impressive showings in Russia.
The 25-year-old is a real talent, and would certainly provide West Ham with something extra in the final third this season.
River Plate currently have Quintero on loan from Porto, and are set to activate a £3million purchase clause in his deal, and his release clause at River will then become €22million (£19.5million).
That would represent fantastic value for the Hammers, and the Colombian playmaker would surely flourish at the London Stadium, what with the West Ham fans' love for creative and expressive players.
The east London outfit are in desperate need of more creative guile in the middle of the park, and Quintero would be the ideal fit to accompany two more defensive-minded players as part of a midfield three.
West Ham are undoubtedly going places under Manuel Pellegrini, and the addition of Quintero really could signal the start of a new era of success at the London Stadium.
