The comments came in the wake of both teams facing each other in Glasgow on Wednesday night, with Barcelona’s superstars running out comfortable 2-0 victors.
The two sides know each other pretty well having played each other 12 times in the last 12 years, between appearances in the Champions League and UEFA Cup/Europa League.
And after getting to know Lawwell, Bartomeu is in now doubt that, in his opinion, Celtic are extremely lucky to have him steering their ship.
Speaking via the Scottish Sun, he said: “I know Peter well. He is one of the best sports leaders in European football – and I do not say that lightly.
“He is quite incredible. I know him through my work on the ECA board so I see him often at meetings.
“When Peter talks, you should listen. He always speaks with a keen intelligence.
“He knows business, but he also understands football and how football works.
“I am not a member of the Celtic board, obviously. But if I was then I would go forward with confidence because he is a man who knows everyone in European football.
“That knowledge and expertise must give Celtic so much confidence as a club.
“He understands the landscape but he is also able to speak well and represent the interests of his own club.”
Lawwell has went through something of an up-and-down relationship with the Celtic supporters during his tenure at the club, with many of the opinion that he doesn’t push the boat out far enough for transfers.
But will a ringing endorsement from the man in charge of a superpower like Barcelona change some doubters’ opinions of Lawwell?
