Liverpool have dropped their price for midfielder Marko Grujic amid transfer interst, according to A Bola.
The Reds’ asking price started off at €20m (£17.2m), but, has dropped the figure due to their keenness on selling the Serbian.
The publication have gone on to claim that a move to Porto has not been ruled out by the Liga NOS club.
This is because Sergio Oliviera could be on his way out of the Stadium do Dragao.
However, Porto still believe the current asking price, between €15m and €17m, is too much.
The Portuguese outfit announced last week that their manager Sérgio Conceição had extended his contract.
Grujic claimed he was left confused by Jurgen Klopp last summer.

TBR View: Grujic transfer could help start off summer clearout
The potential transfer of Grujic to Porto can help the Merseysiders start off their summer clearout.
There are a number of players who have enjoyed an elongated stay at Anfield and need to be sold.
The likes of Divock Origi, Harry Wilson and the Serbia international have remained at the club without much of a future.
However, the willingness to drop their asking price means Liverpool have messed up.
Following his loan spell with Eintracht Frankfurt, Grujic’s value stood at a fairly high price.
But, Liverpool insisted he wasn’t for sale.
The club then went on to further strengthen their midfield with the signing of Thiago Alcantra on a free transfer.
In the same window, Grujic’s already bleak Liverpool future got even bleaker.
And now, following his stuttering loan move to Portugal, the Serbian’s value has fallen.
The inability to approve the transfer of Grujic has meant Liverpool have lost out on money.
Whilst it’s not the end of the world, it shows off poor planning in the transfer market.
A potential sale of Grujic could kick start an important summer for the Reds, who are in desperate need for a revival.
