According to the article there´s a lot of moving pieces: he's started getting more minutes at Benfica, so if he continues in good form through the Spring, Benfica may not want to transfer him when the window opens again, especially to a club that dragged it feet trying to lower the price like Celta apparently did. According to the article, Benfica´s coach stopped the transfer. Also, it is notable that the article refers to him as "Celta´s stellar transfer for this summer" despite the fact that the deal apparently was for 4 million plus an extra 4 depending on milestones. That sounds super low for a mid-table LaLiga team, but COVID19 may have changed the soccer world momentarily. Or the article is BS.
