Mark Schwarzer was a fine goalkeeper in his prime.
The Australian twice made European finals, coming one game from glory with Middlesbrough and Fulham, before picking up back-to-back Premier League winners' medals without playing a single league game for Chelsea and Leicester City in their victorious seasons.
He was a solid choice as a pundit on Match of the Day, and offered some insight on goalkeeping and set-piece defending when he joined former Cottagers teammate Danny Murphy on the sofa.
But one of Schwarzer's comments wasn't quite as well-received as the rest.
With a number of Premier League goalkeepers impressing over the last seven days - not least
Hugo Lloris and Kasper Schmeichel during their respective sides' Champions League outings - the subject of the best number one in the league was raised.
Schwarzer opted for Petr Čech - someone who certainly has laid claim to that honour in the past, but a goalkeeper who plenty of rivals' fans don't seem to think should even be part of the conversation.

Now, those of you with decent memories may recall that Schwarzer doesn't seem to be the biggest David de Gea fan out there.
The 44-year-old was quizzed on the Spaniard's abilities earlier this year on BT Sport's 'Fletch & Sav' show, and
was less than complimentary.
Still, there's probably a bit of a difference between rating De Gea below Manuel Neuer - the best in the world in some people's opinion - and giving Čech the upper hand.
You know what they say, though. Football is a game of opinions.
