Gruda and El Aynaoui have drawn lots of admiration since joining Leipzig, with a permanent transfer seemingly inevitable.

RB Leipzig's obligation to buy Brajan Gruda for €25million will be triggered during the second half of the season, Sky Germany understands.

Meanwhile, the activation of the purchase option for Neil El Aynaoui for the same figure is also considered highly likely.

The pay-TV channel notes that entire club is raving about the Moroccan, who joined from AS Roma last summer, both on and off the pitch.

If things continue the way they are under coach Martin Demichelis, both players will cost around €50million in total next summer.

Follow-up contracts have already been negotiated with both Brighton & Hive Albion as well as Serie A outfit AS Roma.
