I don't mind them waving their arms about. It's when they can't speak properly that irks me.
Watching the recent semi final between Netherlands and Croatia and the co-commentator was ex England Women's team member Fara Williams. There does not appear to be a letter 't' in her alphabet as she was banging on and on about opportuni'ies and qualit'ies. She also had trouble pronouncing Croatia - kept saying Coratio and she also gave a lot of praise to one of the 'Coration players', Moderic. And i had to wonder if he was any relation to Luca Modric who was also on the field at the time.
Having said that, she wasn't on camera so she could also have been waving her arms about like a windmill on speed, for all i know:-)
