Tommy Wright in the frame for Motherwell job

Robinson quit after a 2-0 home defeat by Kilmarnock left Motherwell without a win in nine matches and in 10th place, two points above Scottish Premiership bottom club Hamilton – their opponents tomorrow.

Keith Lasley will be in charge for the Lanarkshire derby and the long-serving former skipper is a strong contender to succeed Robinson, while former St Johnstone manager Wright was quickly installed as bookmakers’ favourite.

Motherwell revealed Robinson had approached the board after Wednesday’s defeat, giving an “honest assessment” of their situation and “stated his desire to leave”.

A club statement added: “It is with regret that the board accepted his resignation, having carefully considered his reasons for wanting to leave his post.

“Despite the current restrictions, the board will now run a thorough process to identify the right person to take the manager’s post.

“This will move at pace, mindful of the busy fixture list and the January transfer window’s impending opening.”

Robinson thanked the club for their support and listed the achievements of himself and his staff, before adding: “We cleared the club’s external debt through player sales, cup runs and league positions. The club has numerous assets going forward, and I’m sure that they will have a strong finish to the season with the brilliant coaching staff currently there.

“My goal was always to leave the club in a healthier position. I believe the staff and I have done this.

“I now feel it is the time for someone new to take the club forward as I feel I have taken it as far as I can.”

Chairman Jim McMahon hailed Robinson for delivering or exceeding targets each year with his transfer record ensuring the club were in a “strong financial position”.

“It has been a privilege to work with him over these years,” he added. “We all wish him well for the future.”

Motherwell were in the top six a week ago before, temporarily at least, losing six points after St Mirren and Kilmarnock appealed against punishments for breaching Covid-19 rules.

They were seconds away from beating Dundee United on Saturday and they dominated the majority of the first half against Killie.
