The 19-year-old midfielder produced another man of the match display as his side beat Livingston 3-2 in their final game of the Scottish Premiership season.
Turnbull set up their first goal before scoring two himself – and actually could have had a hat-trick had he not missed a penalty too.
And that made it 15 goals and four assists in 30 appearances for the Motherwell man this season.
Fir Park CEO Burrows spoke after the game about Turnbull and the inevitable interest in him from other teams.
In Burrows’ view, it’ll need to be more than the £1.75million Celtic paid Motherwell for Phil O’Donnell in 1994 to tempt them to sell.
Per bbc.co.uk, he said: “It would have to be more than that
“If anyone is wanting to David Turnbull, the fee would have to be significant. Not only because of his talent, it’s to do with the contribution to the team.
“It would need to be a figure the club just couldn’t refuse, and that’s not going to be cheap. I would imagine it will set all sorts of records for this football club.”
Burrows added: “Of course we are trying to build the team around David because he is an exceptional young talent.
“He is in not just a once-in-a-generation talent, he’s once-in-a-couple-of-generations talent.
“I think he is that good, I very much hope he may be involved in the Scotland set-up in the summer. I think he is ready for that.
“I don’t know if anyone is going to bid, what I can tell Motherwell fans is that at this point nobody has done anything.”
Given Turnbull’s form, it’s clear that there will be teams interested in signing him this summer.
His contract runs until 2021 so there’s no worries that Turnbull will depart at the first sign of interest like Jake Hastie did when he signed a pre-contract with Rangers to make a move there this summer.
