Porto star Hulk is back on the agenda for Manchester United.
O Jogo says United boss Sir Alex Ferguson is planning to raid the Portuguese market again to boost his strike-force.
Brazilian Hulk is being watched regularly by United scouts after a stunning season which has seen him to score 19 goals in just 20 games.
The centre-forward has spoken in the past about an ambition to test himself in England, where Manchester City football chief Mike Rigg has also confirmed their interest.
