There can be no doubt that Peter Lawwell has delivered during his time at Celtic – those who argue otherwise are simply “shortsighted.”

That is according to finance guru and Football Insider columnist Kieran Maguire, speaking exclusively with Lawwell’s 17-year reign at Parkhead coming to a bitter end.

Last Sunday, the 61-year-old was the victim of an arson attack on his property which investigators have confirmed was deliberate.

In a statement released via Celtic’s official website, the outgoing chief executive wrote that he and his family had been “deeply affected” by the disturbing events.

Attitudes towards the long-standing Celtic supremo have soured over the last 12 months and he announced in February that he would retire at the end of the season.

Maguire insists that Lawwell’s tenure at Celtic has been a riotous success, on the pitch and in the commercial department.

He told Football Insider correspondent Adam Williams: “Lawwell has been Dermot Desmond’s eyes and ears on the ground.

“He made Celtic more competitive by addressing poor areas of cost control and extending the brand to generate additional revenues. So from a business perspective, he has delivered.

“Some Celtic fans have not appreciated the last 12 months. It hasn’t finished well but it’s very shortsighted to say that he hasn’t delivered.

“To have won nine Premierships in a row is a brilliant achievement.”

In the same statement, Lawwell thanked supporters for the “thousands of messages of support” he received.

Former Scottish Rugby chief Dominic McKay will replace him in June.
