It is known that Celtic is one of the clubs that is behind Brenden Aaronson and Mark McKenzie steps. Last night both had a great performance, once again. The striker scored a fantastic goal from outside the box and McKenzie managed to keep a third clean sheet in five games.

According to Daily Record, Aaronson has been linked to a host of sides around Europe. In addition to this, Celtic would have asked to be kept informed of McKenzie´s developments.

However, reach a deal could be difficult for the striker. Others clubs like Borussia Dortmund, Monchengladbach, and Hoffenheim seems to be interested in him. On the other hand, it is believed that McKenzie should leave sooner: the centre-back has openly said that he wants to move to Europe.
