Dortmund could "well imagine" swooping for Union Berlin defender DoekhiRTL/ntv and Sport.de are both reporting that Borussia Dortmund have already spoken with Danilho Doekhi regarding a summer transfer.It's believed the Westphalian giants could "well imagine" signing the central defender who currently plies his trade with 1.FC Union Berlin. Since the 27-year-old's contract with the Köpenick club is expiring when the season ends, he would be available on a free transfer.Back in winter, clubs including Lazio from the Serie A and Bundesliga side VfL Wolfsburg were interested in the Dutch native. Doekhi's fine form has continued too, scoring in yesterday's 1-3 defeat against RB Leipzig – amassing his seventh goal of the season.The defender has not yet made a decision regarding the next step in his career, but it's clear staying in Berlin is out of the question.
