Liverpool are beginning plans to sell players in order to fund the club's summer transfer window budget, with Marko Grujic set to become the first to depart Anfield.
As per The Athletic's reporter James Pearce, the Portuguese club, like many across Italy and Germany, are eyeing a move for Grujic.
It's also believed The Reds will aim to get £15 million for the 25-year-old.
Grujic, who was on loan last season at FC Porto in the Primeira Liga, only featured twice in the League Cup for Liverpool last season and it looks like he will be sold to bolster the club's transfer funds.
The Reds signed him from Red Star Belgrade for £5.1 million in January, 2016, but his five year spell at Anfield has only earnt him 16 appearances for the club.
Grujic has had loan spells at Cardiff City, Hertha BSC and Porto, but will definitely bring the club a profit since being signed as a 19-year-old.
Liverpool's sporting director Michael Edwards has successfully bumped sales for the likes of Christian Benteke, Dominic Solanke and Jordan Ibe.
However, due to the economic effects of COVID-19, it may be harder to do so this summer.
The belief around the club is that The Reds can raise £60 million from Grujic, Divock Origi and Harry Wilson.
Both the latter have been named in their nations 26-man squad for the upcoming UEFA EURO 2020 tournament, and it's a great chance to bump up their price if the players perform well.
The likes of Taiwo Awonyi, Loris Karius, Sheyi Ojo, Liam Millar and Ben Woodburn may be moved on as well, but none are likely to sell for big fees.
