Porto defender Pepe has suggested he could be following Anderson to Manchester United this summer.
The Brazilian-born defender, a favourite of Chelsea manager Jose Mourinho, is set to gain his Portuguese passport and join Luiz Felipe Scolari's national team.
Asked about the possibility of facing his old teammate, Anderson, in the future, Pepe told Maisfutebol: "We could also be teammates. Football works in many ways.
"I have a contract with Porto and I am happy. But if a good offer arrives, we will have to sit down and consider it."
