Dundee boss Neil McCann expressed disappointment over Celtic leaving it till the last minute of the transfer window to buy Jack Hendry.
The 22-year-old centre-back joined the Scottish champions late on Wednesday night for a fee which beat the Dens Park record of £1.2million paid by the Parkhead club for goalkeeper Robert Douglas in 2000.
McCann described Hendry as a “good fit” for Celtic, but noted that he was left with no time to bring in a suitable replacement.
Ahead of the home Ladbrokes Premiership clash with bottom side Ross County on Saturday, he said: “I was never ignorant to the fact that, if you are doing well and players are playing well, then big clubs come calling.
“They did. The disappointing thing for me was how late in the day Celtic left it to decide to get their business done.
“It left me with no time whatsoever to get any business done myself.
“I was desperate to keep Jack, but I was mindful that should Celtic come in with the right offer that the club can’t turn down, I have to have someone who can step in and bolster the squad.
“I wasn’t allowed to do that because I can’t sign a player at one minute to 12 because it takes a bit of times to go through and by that time these players may have other options.
“But a club record fee for Dundee is a huge amount of money and I am proud this club gave Jack the opportunity to showcase his ability.”
