Charlie Nicholas believes Arsenal have paid over the odds for Kieran Tierney .
The Celtic star is having a medical in North London ahead of sealing his £25million move to the Premier League giants.
But former striker Nicholas – who played for both clubs – insists the Gunners have splashed too much cash for Tierney.
And he has told Celtic supporters to get real, with many disappointed the 22-year-old didn’t stay to help his boyhood favourites over the line in the chase for 9 in a row and potentially the fabled 10.
Nicholas said: "He would be much better than what Arsenal currently have.
"My honest opinion is it’s quite a high price. Celtic have got very good value at £25m.
"I know Celtic fans say he’s worth £40m because of how much (£50m) Aaron Wan-Bissaka went to Manchester United for.
"He’s played in the Scottish Premiership, he’s a treble Treble winner and an absolute diehard Celtic fan but the time is right for Kieran to move on.
"Fans might sit and say, 'Why does he not stay for 9 in a row'. But there’s no guarantee of Celtic winning that. Neither is 10 in a row.
"OK, you can’t guarantee trophies at Arsenal either but what I can say as an Arsenal fan is they’re signing a very talented left-back who will get better. Arsenal will make him better.
"And the club had to make a statement of intent defensively because they’ve been lacking in that department."
