Porto's bid to secure the signing of Alfredo Morelos could reportedly be boosted by English Premier League giants Liverpool.
Jurgen Klopp's side remain keen on midfielder Otavio who carries a £60m asking price after a brilliant season in Portugal.
But it's been reported Liverpool could land him for a reduced fee of around £34m if they strike this summer.
Spanish outlet Marca state a deal for Otavio would "unlock" the door Porto in their bid to secure Morelos with the Rangers hero emerging as their No.1 strike option.
Record Sport understands his agent was recently in Portugal over discussions with other clients rather than working on Morelos' future.
A fee of £10m has been mooted but that is unlikely to get the attention of Rangers with Steven Gerrard and Ross Wilson looking to build ahead of their Champions League qualifying tilt.
Morelos was the subject of a bid from Lille last summer but remained in Glasgow and would go on to play a pivotal role in the club's first title success in a decade.
Porto are aiming to top up their squad after exiting Financial Fair Play sanctions and they have some room for manoeuvre on the transfer market.
If Morelos heads to the Estadio Dragao he will be joined by a familiar face in former Ibrox team-mate Fabio Cardoso, who is on the verge of joining from Santa Clara.
