Should RB Leipzig make Christopher Nkunku's return permanent?

Leipzig are very happy with Nkunku's performances, and the Frenchman himself would like to stay at the club beyond this season.

With a €28 million purchase option in his loan deal from AC Milan, a permanent return is looking increasingly likely.

Considering what Nkunku has already shown so far, would you activate the purchase option now, or wait until the end of the season before making a decision?
