Celtic's newest signing Adam Matthews insists he could not reject the SPL giants once they came calling.
Although the former Cardiff City man was attracting Premier League interest, the sheer size of Celtic meant that making the switch to Parkhead was a 'no-brainer'.
Matthews has been criticised for not furthering his career in the England's top flight, however, he has defended the move by stating the club's fan base is as big any club's.
"I just think it's the size of the club and the supporters," explained Matthews.
"They have a massive fan base all over the world. They are one of the biggest clubs in the world so that was the main factor.
"They are the second most supported team in the world so it was a no-brainer.
"Any player would love to play for them. I don't think anyone could turn down the chance to play for them."
Matthews will be linking up with ex-team-mate Joe Ledley while Craig Bellamy, who had a stint on loan at Celtic, also had positive words to say about the club.
The 19-year-old has already experienced the Old Firm atmosphere and he is now looking forward to getting started with his new club and impressing the club's fans.
"I spoke to him (Ledley) before I signed and he said: 'The club is massive, you won't know what's hit you until you're up here'. He is enjoying it up here," he continued.
"Craig Bellamy said the supporters were great, they treat you well if you treat them well.
"I came up to watch the Celtic-Rangers (League Cup) final at Hampden, the atmosphere was amazing. I just cannot wait to get involved and play in the game.
"The only real derby we have is Swansea. That's a massive derby but I think this one tops it.
"I don't think I have been to a game where the atmosphere was so good. I couldn't hear myself speak."
