The two clubs have been locked in negotiations throughout the transfer window, yet it seems they are still unable to reach an agreement.
One thing that has been holding up the move is the structure being proposed, as it will be a loan to buy option, though the Baggies only want that to stand if they stay in the Premier League, while Benfica feel it should be automatically triggered.
It has now been revealed that there is even a disagreement regarding the amount West Brom will need to pay if the clause is eventually triggered. This comes with West Brom wanting to pay €6m (£5.6m), while Benfica are holding out for €10m (£9.3m).
With all of the above considered, it seems as though there may be a while yet until the two sides are able to reach an agreement to see the Croatian return to The Hawthorns.
If Krovinovic does return, it would see him follow Grady Diangana, Matheus Pereira and Callum Robinson, who have all come back after loans from West Ham United, Sporting CP and Sheffield United respectively.
