Celtic are reportedly eyeing up a move for Porto right back Fernando Fonseca.
According to the Scottish Sun, the 21-year-old is viewed as a possible long-term replacement for Mikael Lustig. The Swede is out of contract this summer and has been linked with a move to AIK Stockholm.
Fonseca currently plays for the Porto B-team and is under contract until the summer of 2020. The 21-year-old, who was previously linked with a move to Juventus, would be available for around £2 million.
In recent weeks, Celtic were also linked with Atalanta's Belgian fullback Timothy Castagne. However the Serie A side's valuation of £10 million priced Celtic out of a move.
Brendan Rodgers's team were also said to be interested in Olympiacos defender Omar Elabdellaoui. However, the Greek side were unwilling to let the Norwegian international leave.
