Ex-Celtic star Adam Matthews has described his time at Parkhead as the best of his career.

The Welsh defender enjoyed four years in Glasgow as a Hoops player and will always remember it fondly.

He won six trophies in a Celts jersey and starred on that famous night where Neil Lennon's men turned over a Lionel Messi-inspired Barcelona side.

Now a Charlton player, Matthews has recalled his time at Celtic and remembers the big games against Rangers and in the Champions League.

And he admits he found it tough to say goodbye to the Scottish champions when he left for Sunderland in 2015.

"It was a great honour to sign for Celtic. It was unexpected, it came out of the blue," he told London News.

"They are a huge, huge club. People say the league is not great and blah, blah, blah – but any football game is tough.

"I loved every minute of it – playing in the Champions League, Europa League and the Old Firm matches. 

"It was definitely the best moments of my career.

"I was sad to leave."

Matthews also remembered the tremendous atmosphere back in 2012 when his side beat Barca thanks to THAT Tony Watt goal.

"It was a weird feeling," he added. 

"You’re star-struck but there is also so much Adrenalin that you feel extra sharp. The crowd was so loud at Celtic Park you couldn’t hear the Champions League music as you walked out.

"We had to concentrate for 90 minutes and everyone who played that night did that.

"We went for a couple of drinks afterwards in a local Glasgow bar that stayed open for a couple of hours. Nothing too mad because we had a game at the weekend."
