Tielemans was already on a yellow when he fouled Wilson and is usually used as a 'final warning' to the offending player. Not this time, no second yellow was given. Was the 'challenge' intentional? Obviously as Tielemans jogged away with a smirk on his face. It was a deliberate attempt to put one of Bournemouth's key players out of the game.
Re. our 'penalty' on Saturday. From where I sat (centre of SS) I couldn't see what happened, but I knew from the reaction of the players and fans on the kop that there was something in it. Did Mason have a clear view? Did he - in a split second - 'compute' that the Southampton players' handball was 'unintentional' or that 'his body shape was unnatural'? Of course not. As you say, this is what VAR was meant to be there for but is just being used as an excuse to back up referee's poor decisions.
Don't forget that we've already been denied a penalty v Palace when Stevens' shot was charged down by a defender who's arms/hands were obviously used to 'enlarge' his body shape:

If VAR is to survive, there must be more transparency and communication with the fans. It's no good if these incidents aren't seen from multiple angles and zoomed in on the big screen instead of an areswipe like Mason just sticking his finger in his ear and giving the wrong decision. Incidents like these are just a cop-out for the ref. - aided and abetted by 'the referee's friend' - VAR.
