I flicked between the Celtic and the Arsenal games. The Celtic game I thought WAS just like a parks game with mistakes galore and could only manage 10 minutes.
Possibly Chris Sutton's commentary had an affect on me too mind!
The Europa league IMO is not worth bothering with until the knock out stages. I find it football overload otherwise.
Didn't watch the Rangers game as I could never stand to watch them, even when they were 'good'.
