cana flies in yes, but very rarely if you watch french football as often as I do then you will see how often he flies in and how often he makes great tackles. Cana flies into tackles when his team are losing, he gets the crowd going and starts to show the team his passion, somehow the team then starts to get back into the game. Watch some matches where marseille are losing and youll see how often cana makes a tackle that raises the crowd and how often they come back to win.
It may seem stupid but that is what we are lacking sometimes, I mean when neville made that tackle on ronaldo last season, he flied in and that got the fans fired up and on the teams side which raised the teams performance in the match. That is why we need cana he can be that inspiration towards the fans and team.
