"Itâ00s a big boost to have Peter back for a game like this. Itâ00s a pivotal game in the Six Nations for us and this is the one you want to have a full deck for. If we win weâ00re right back in the hunt again," explained O'Sullivan.
â00Peter is probably the best passer of the ball in the world at number 9. He gives the receiver so much time. The odd one goes astray but when you pass the ball 60 or 70 times in a game thereâ00s going to be one or two off target.
â00He has a capacity as well to get us out of jail. Heâ00s done that a couple of times in big games where thereâ00s been massive line breaks when you could see nothing but a try coming, and he comes out of nowhere and takes somebody down with a hand trip.
â00Itâ00s not the dog in the fight, itâ00s the fight in the dog with Peter. He does box well above his weight all the time. He puts in a huge number of tackles and always tackles people that are bigger than him because thereâ00s nobody smaller than him on the pitch."
Despite his size, Stringer cuts an authoritative figure behind the Irish scrum and his presence and experience - tomorrow will mark his 74th cap - will be vital in the so-called 'championship minutes' against England.
O'Sullivan added: "Heâ00s a good organiser, he barks at the pack and keeps them in line and theyâ00re all afraid to cross him and that dynamic is very important in a pivotal position.
"Isaac Boss had a fine game the last day but Peter has that extra edge of experience and he knows most of the pack that bit better than Isaac, having played with Munster.
â00Thereâ00s a little bit of pressure on Peter because he knows he has to put in a big game after being out of commission for a few weeks, but he is one guy I wouldnâ00t worry about under pressure. He tends to get on with his job and the bigger the game the harder he works.
â00Thatâ00s why itâ00s good to have him back. Itâ00s a good settling influence in that area of the field for us I think.â0
