The Newcastle head coach has been discussing his boss.
Indeed, after the signing of Florian Thauvin was confirmed by the club, McClaren was left impressed by the Newcastle owner's actions in the transfer market.
And he feels the Tyneside outfit have delivered 100 per cent in terms of their recruitment going into a challenging Premier League campaign.
The Newcastle boss is quoted as telling reporters: "After Mike Ashley’s words, I think people were doubting and those doubts were still there at the beginning of pre-season, especially when I first came in.
"There were a lot of doubts and comments that it was all talk, but I think the club have delivered. They’ve absolutely delivered 100% with the quality that we’ve got."
Newcastle's summer spending so far has obviously been a credit to Ashley's promise. But the suggestion he has proved his critics wrong is perhaps a little premature from McClaren.
Naturally, the Magpies boss needs to fill column inches - not to mention publicly praise his employer - but the Newcastle owner's reputation won't have changed overnight.
As well as a lack of investment in recent years, the St James' Park outfit's big problem has been a misuse of resources in the transfer market. And, until the likes of Aleksandar Mitrovic and Thauvin come good on Tyneside, that will remain the case...
