I personally think Mykolenko should be given licence to get forward and given a chance to show his worth until the end of the season as first choice left back.
Since Dyche has left, it's clear that he was not liked (to say the least) by the entire squad. It's also clear that he asked his defenders to defend and defend only, and his strikers and number 10s to first focus on defence before thinking of attack - so no surprise the team couldn't score.
Mykolenko can actually swing in a good ball, and if he's given the opportunity to get up the wing while the rest of the defence shifts over one position to the left and our number 6 stays put in the middle of the park, he might have a chance to strike a partnership with whoever is playing left wing.
It's worth a shot anyway imo.
