Premier League clubs are on red alert after PSV Eindhoven allowed Jonathan Reis to fall out of contract.
The Brazilian centre-forward has been linked with Fulham, Everton and Liverpool this past season - and can now be snapped up as a free agent.
Agent Renato de Moura Ricardo is stunned PSV failed to secure Reis to a new deal.
"We have heard nothing, the option has not been exercised," he said. "Jonathan is a free transfer."
