The Hoops drew 0-0 with Benfica a fortnight ago and beat Spartak Moscow 3-2 in Russia on Tuesday night and Lennon feels those results have gone a long way to suggest that Scottish football is no longer second rate after a few years in the football wilderness.
"I hope people down south take notice. It's not a backwater league any more. There are some quality players playing up here," he said.

"All we can do is answer with performances like the one in Moscow."
