Liverpool are being linked with a move for Porto midfielder Fabio Vieira.
The Reds have already had transfer business with Porto, having signed Luis Diaz in the January transfer window. Liverpool agreed a £49m deal with the Portuguese club to bring the Colombia international to Anfield.
Now, according to a report in the Sunday Mirror, Liverpool could be about to do further business with Porto. It has been claimed that the Reds have reached an agreement to have the first refusal to sign attacking midfielder Vieira.
