I know where Rurik is coming from on Klavan as I think he didn't put a foot wrong and made some smart passes, blocks and presses, normally he'd be in my top 3, but...
Coutinho - world class display
Salah - Like Suarez at times tonight with his jinks and link-up play
Mane - Very sloppy at times and obviously not as sharp in the link up as the other 3 up top, but worked his knackers off and both of his goals were superb.
