Manchester United remain in pursuit of Benfica starlet Umaro Embalo.
The Mirror says United chiefs have been keeping tabs on the young forward, born in Guinea-Bissau.
The Red Devils sent both chief scout Javier Ribalta and head of development John Murtagh to watch the youngster in early December.
United bosses also witnessed his talent first hand earlier in the season, when Embalo appeared against United in the UEFA Youth League.
However, it's reported that RB Leipzig sporting director Ralf Rangnick and sports coordinator Jochen Schneider visited Lisbon on Tuesday for talks with Benfica president Luis Felipe Vieira over a potential deal for another of Europe's biggest youth talents.
