Celtic's Brendan Rodgers evades question about club's ambition
Brendan Rodgers has refused to say if his ambitions for Celtic are being matched by the Scottish champions' board.
It is understood the Celtic manager is unhappy about the Glasgow club failing to secure summer signing targets, including John McGinn.
The Scotland midfielder was sold by Hibernian to Aston Villa on Wednesday.
Asked if the board match his ambitions, Rodgers said: "I wouldn't answer that. It's private."
Comments Rodgers made earlier this week have not gone down well with members of the Celtic board, who are proud of their track record in the transfer market.
Talking before Saturday's trip to Tynecastle to face Hearts in the Scottish Premiership, the Northern Irishman was asked on Thursday if it was an ongoing challenge.
"I've got a huge respect for the people that work at this club - the board and the directors," he said. "They've created a very stable foundation and I have to respect that.
"Of course, as a manager, I always want the club to be the very best it can be for the supporters, but I have to maybe understand where the limits are sometimes."
Celtic had bids rejected by Hibs for McGinn before the midfielder headed for the English Championship club managed by Steve Bruce.
Rodgers revealed that he "spoke to him at length" on Thursday and wished him well in England.
"The only thing I have to say with young John is I wish him all the very best," Rodgers said. "In the two years I have been here, has he developed into a first-class player.
"As a Celtic supporter himself, I would love for him to be here working and playing, but it wasn't to be."
Celtic's only signings so far this summer are striker Odsonne Edouard from Paris St-Germain, and goalkeeper Scott Bain from Dundee, both of whom were on loan to the club last season.
