When Harry Redknapp first signed the Frenchman I was a little skeptical. Centre back wasn't our weakest position in the squad and his performances for Tottenham last season left much to be desired.
It looked like my worries would be confirmed early in the season as he was utilised by Redknapp as a centre midfielder as Chelsea and Man City battered us.
But when Kaboul was allowed to play in his natural position he impressed me and other Pompey fans with his calm defending and ability to track back and challenge some of the faster players Pompey have been up against this season.
He has been just as impressive (if not, more so) when playing at right back. Again, I had my reservations when he first featured there against Everton but he did a stellar job and even showed he can match Johnson in the attacking stakes with a brilliant goal against West Brom.
Sure, Younes has made mistakes this season and his willingness to go forward means we're sometimes caught short at the back. However, I can'tny glaring errors he has made and he's only 23 so has plenty of time to iron out those problems and become a top class defender.
With Sol Campbell almost certain to leave the club at the end of the season it is reassuring to know we have a ready made replacement in Kaboul to take his place (should he stay himself) and with more games under his belt he should only improve his game.
We may have had serious questions at the start of the season but it looks like that Kaboul may well be a reported £6 million well spent.
