Well, that puts the Fletcher vs O'Shea debate to bed, at least
“John O’Shea is the same. The two of them have matured to the level where they are now key players for our club."
I wouldn't put any stock into what a manager says about a player while they're still at the same club. It's just a record of what they think the player needs to hear, not what the manager believes. Not saying it isn't true in this instance, just that there's no way of knowing.
