FORMER Celtic striker Tommy Coyne has warned new Bhoys Stuart Armstrong and Gary Mackay-Steven that they are about to experience a whole new ball game.
The Dundee United double-act arrived on the last day of the transfer deadline on Monday.
Coyne took the identical journey to Parkhead when he left Dundee for the Hoops in 1989.
Billy McNeill paid the Dens Park outfit £500,000 for the striker who had never attempted to disguise his affection for the team from the east end of Glasgow.
But Coyne admitted he was prepared for what lay in store – Armstrong and Mackay-Steven will have to learn fast.
He said: “I would imagine it will be a huge culture shock for them.
“It didn’t really surprise me as I’m from Glasgow. But they are from the Highlands.
“The biggest eye-opener for them will be the daily pressure of playing for Celtic, the expectancy to win every game – even if it’s Barcelona you’re playing.”
The £2million pair will have to sit out tomorrow’s Scottish Cup Fifth Round tie against Dundee at Dens Park as they are both Cup-tied.
Ronny Deila may give them their debuts in the SPFL encounter with Partick Thistle at Firhill on Wednesday.
