I think he'll find it tough. Sol Campbell is the captain and has added strength and presence to the back four, so it's a certainty that he will start every game he is available for.
He's also going to find it very difficult to displace Sylvain Distin too. In my opinion, Distin has been our most impressive and consistent performer over the season so far. He reads the game well, is good in the air, can tackle players.
However, the biggest asset he has over Linvoy is his pace. Speedy strikers such as Henri Camara can get away from Primus but I doubt he could do the same to Distin. Harry likes pace in his side and this is only one reason why the manager isn't going to drop him any time soon.
Linvoy does have a trump card though, and that is his versatility. The 34-year-old can play at right back if needed and with Lauren being so injury prone, Johnson being prone to losing concentration and Cranie being inexperienced, he might be able to get back into the side that way.
Sol will probably end up being injured again during the season too, so Linvoy will be able to slot in there but the question is can he keep his place if and when he wins it back?
It's not a new situation for the Pompey fan favourite. Time after time he has proved his doubters wrong by forcing his way back into the side when it was thought that he wouldn't see the first team again.
But getting into this Pompey defence will be Linvoy's toughest task in his career. If only he was left-footed....
