The Brazilian news outlet claims that Vasco are trying to offload the 20-year-old before the end of the year and are hoping to make over £10.7million from any potential deal.
It is understood that Porto have also approached the financially-challenged Brazilian club about Marrony, who is a centre-forward that can also play on the wings.
UOL adds that although Marrony is on the radars of both Newcastle and Porto, no official bid has been tabled for him just yet.
Newcastle need to continue beefing up their squad before the summer transfer window slams shut next Thursday and Steve Bruce is currently short of options in most areas of his squad. Marrony is a versatile young player who could prove useful for a team like the Magpies as he plays primarily as a striker but can also feature on the wings. Marrony’s lack of senior experience and lack of goals should be a concern though. Although he’s young, Marrony has only scored two goals in 32 first-team appearances for Vasco da Gama. One of those goals came last week when he played 90 minutes up front and scored in a 1-1 draw against Palmeiras. It’s a good time for him to hit a good run of form amid this interest from Europe but even if Newcastle did want to sign him, Marrony’s lack of international caps for Brazil – even at youth level – could hinder his progress in trying to earn a UK work permit.
