Mark Clattenburg shocked a lot of people with appearance on BT Sport

We've seen Mark Clattenburg on our TV screens literally hundreds of times over the years.

You'd imagine you'd know quite a bit about the veteran referee but, as it turns out, you might not know the first thing about Clattenburg. Clattenburg stepped away from the Premier League last season to take up a position as Saudi Arabia's Head of Refereeing. https://twitter.com/JOE_co_uk/status/842503495475519488 And he's earned a shiny new television gig too. Clattenburg appeared on BT Sport on Sunday, when he was tasked with offering up his refereeing expertise for the in-studio panel during the Community Shield game between Premier League champions Chelsea and FA Cup holders Arsenal. The match had plenty of talking points for Clattenburg to cast his eye over, including an incident which saw Willian booked for simulation when subsequent viewing suggested there was slight contact. https://twitter.com/btsportfootball/status/894197855094800385 Viewers, accustomed to seeing Howard Webb in front of several screens, were surprised to see Clattenburg in Webb's seat, giving his opinion. And they were even more shocked when he opened his mouth and a Geordie accent came out. Most supporters hadn't seen Clattenburg give an interview before so were astounded to hear what he actually sounded like. Not only that, but the tone of his voice did not exactly feature the booming authority that fans might have expected. https://twitter.com/mrmarkkilgallon/status/894172297447313410 https://twitter.com/PricelessGooner/status/894197150455922690 https://twitter.com/CusackOscar/status/894198423800479744 https://twitter.com/mark_omeara89/status/894196395426623488 https://twitter.com/rossbramble/status/894196347993247747 https://twitter.com/LincolnRamirez/status/894192060948992000 https://twitter.com/mrbentaylor/status/894191419904188416 https://twitter.com/rajsinghchohan/status/894191873593679872 https://twitter.com/GiNgEr_JaMeS/status/894196345996808192 https://twitter.com/Jackarmes/status/894196316628287488 https://twitter.com/stighefootball/status/894191566587351041
