Fair enough. :)
You get no time on the ball playing for Celtic, it's as simple as that and you can believe what you want.
Shelton Martis: "When I had a word with him afterwards he said to me, 'I'm knackered'. I said, 'Welcome to Scotland'"
Hesselink: "Although I only played for less than 40 minutes, I am still out of breath. The pace of the game in Scotland is unbelievably fast."
...especially as he admitted that he struggled to breathe throughout the final ten minutes, such was the pace of the game.
And that's a home game. Away games would be even worse.
