Manchester United are in talks with Porto over a deal for Brazilian full-back Alex Telles.
United manager Ole Gunnar Solskjaer wants to strengthen his options on the left and feels the 27-year-old would be a useful addition.
Porto want £18m for Telles, who has one year left on his contract and could be signed without a fee on a pre-contract in January.
Telles, who has one cap for Brazil, has scored 21 goals in 127 games for Porto.
