You don't want to get on the wrong side of Graeme Souness. Just ask Thierry Henry.
Last night, after Arsenal's 1-1 draw with rivals Tottenham in the north London derby, Souness took it upon himself to analyse the Gunners' current injury crisis.
Arsene Wenger's side currently have a number of first-team players, including the likes of Alex Oxlade-Chamberlain, Theo Walcott and Aaron Ramsey, out on the treatment table.

And Souness had a theory as to why Arsenal have struggled on the injury scene for some time now.
The former Blackburn Rovers boss suggested that Wenger has a number of players who run with the ball, meaning that the club's stars are more likely to get injured as they often have to extend for the ball as it gets away from them.
But, while Souness' insight into Arsenal's injury problems made relatively interesting viewing on Sky Sports, it was his bizarre outburst towards Herny that really took everyone by surprise. Raising his voice after a slight murmur from Henry, Souness stated: 'I'm talking'.
Souness wasn't happy with his fellow pundit, but it's still extremely amusing for everyone else. It's well worth the watch:
In truth, though, regarding Arsenal's injury problems, Souness may well have a point. The Gunners have a number of fragile players at their disposal and seem to have key men missing season in, season out.
Once again, as the club go in search of securing the Premier League title, injury problems could cost Wenger's side.
