Martin Keown incredibly nieve

What agenda is mMartin Keown working to because he comments on Tottenham signing Moussa Sissoko are incredibly nieve. He questions why we have bought him when he is a similar player to Mousa Dembele.

Has he not considered that Mousa Dembele could get something called an injury and what about playing UEFA Champions League football in midweek, does Mr Keown not feel that the player will need some rest periods after such games?

As a former professional footballer he should have a little more common sense than that, but perhaps that is why he went into the media instead of management, with thinking like that he certainly wouldn't have been able to cut the mustard as a boss.
"I think it’s an awful lot of money for a player who struggled for consistency in his three years at Newcastle. 
"Though having said that, I was surprised by how well he played for France at Euro 2016 and it’ll be interesting to see how Mauricio Pochettino can make it work. The Argentine seems to develop players well. 
"Paying £30million for any player is very uncharacteristic of Tottenham, and given that they’re in the process of building a new stadium, I wouldn’t have thought it was money they can afford to waste. 
"He is also quite a similar player to Mousa Dembele, who was excellent last season, so the whole deal seems a bit unnecessary to me."
