Mo got off to a difficult start with Celtic at the beginning of last season, particularly in his debut against Artmedia in a Champions League qualifier, but he settled down and had a good run before losing his place in the side in November.
Since being substituted in a 1-0 home defeat against Dunfermline on the last Saturday in November he has played just three times and with manager Gordon Strachan keen to bring in a new left back he has been made available.
That has alerted both Leeds and Norwich, with both clubs being keen to bring him back into Championship football, where he previously played for five years, initially for Wolves and then for two years for the Clarets.
It was with us that he got regular football at our level having struggled to get a place in the Wolves side, and in two years at Turf Moor he missed just two league games, both of them because of suspension. Now 31, he will be looking for a move that will again give him regular first team football.
