Roger Mitchell reckons Celtic should take a deep dive to find out what two of the most forward-thinking clubs in European football, Brentford and Club Brugge are doing differently.

The former SPL chief executive and lifelong Hoops fan has called on the club's board to commission two dossiers to establish what can be learned.

Brentford sit seventh after seven games in the toughest league in the world despite having no history of success to speak of. They are owned by betting guru Matthew Benham and have employed data to gain an edge on the competition.

They beat Celtic to the £10m signing of Ivan Toney last summer, with the striker now worth an estimated £50m.

Meanwhile Brugges are similarly forward-thinking, have been champions in three of the last four seasons and have qualified for the Champions League.

Mitchell wrote on Twitter: "There should be two dossiers before the board at Celtic PLC.

"'What they do and we don't' is the heading of both reports.

"First one Brugge, second one Brentford.

"Both clubs would be considered by most Celtic fans as 'not as big as us'. How quaint."
