Part owned by Roma and Cagliari, Roma have made a move this month to secure 100% of his rights from their Serie A rivals - as per RomaNews - and that could have played a key factor in whether Liverpool had any chance to sign Nainggolan.
However, the Reds have to now face more competition if they intend to secure the signature of the 26-year-old, with La Gazzetta dello Sport reporting that Bundesliga side Borussia Dortmund have submitted a €26 million offer for Nainggolan.
With the offer split between both Roma and Cagliari, Jurgen Klopp will have to hope that both clubs accept the potential transfer if a move is to go ahead, although the report indicates that there is no real interest form the player himself concerning a move to Germany.
There is no suggestion as to how Nainggolan would feel if Liverpool made a concrete offer for his services, but the stalling talks between his two current clubs could force the player to seek a move elsewhere if no agreement can be struck.
Brendan Rodgers’ side will likely have to match Dortmund’s bid if they intend to open talks with the eight-capped international, and, if they intend to compete with the German side on a financial level they will have to at least equal their contract offer of €3 million a year to Nainggolan.
Although talks are ongoing between Cagliari and Roma concerning the purchase of player rights, with no indication that a conclusion is near, the report suggests that both clubs want an agreement to be reached as soon as possible.
