Portsmouth are on the verge of signing Portuguese midfielder Manuel Fernandes for a club record £10m, reports BBC Radio Solent.
Fernandes has been hailed as the new Claude Makelele
The 20-year-old Benfica player is expected to have a medical on Thursday before discussing personal terms.
If Fernandes signs the deal would smash Portsmouth's previous record of the £4m paid for Benjani Mwaruwari in January.
Fernandes was set to fly into the UK on Wednesday after Portsmouth reached an agreement in principle with Benfica.
Fernandes is a product of Benfica's youth system who made his first-team debut during the 2003/04 season, under then coach Jose Antonio Camacho.
He was part of the Portugal youth team that reached the quarter-finals of the Fifa U17 World Championship.
In February 2005 he made his international debut for the senior team against the Republic of Ireland but he missed out on selection for Portugal's world Cup squad in Germany.
