David Moyes has refused to rule himself out of the Celtic job as he leads the way as the bookies favourite.
Moyes is thought to still have an affection for Celtic and is keeping his options open before returning to management this summer by remaining quiet on any speculation.
Speaking live on Sky Sports, he said:
Celtic’s a brilliant football club, and they have an unbelievable fanbase – one of the biggest in the world.
I’m going to wait and make my decision in the summertime. There are lots of jobs that would interest me.

The 52-year-old began his career in the green and white Hoops and made 28 appearances in three years before moving on to Cambridge United.
He spent 10 successful years managing 500 games at Everton and guided them to four European campaigns and a fourth-placed finish in the Premier League.
The Scot move to Manchester United in 2013 but was sacked in April as he failed to live up to high expectations in Manchester.
A spell aboard managing Spanish side Read Sociedad will also have given the manager valuable experience, even if his time there was one day shy of a year.
The news follows Ronny Deila confirming via the club website yesterday that he would leave at the end of the season – citing that the club was the most important thing.
Deila won two trophies in his first season and is on course for his second league title this season.
However, his European inexperience has seen him fall short of the expectation at Celtic with fans growing discontent with domestic performances as well.
Deila’s side are in action again on Sunday as Celtic take on Ross County at Paradise as they look to move closer to a fifth successive league title.
