Leinster impressed me. The went to Wembley and won by playing a game an away team should always do by knowing that Saracens would be under preassure, at home and well up for a physical game, Leinster played a great deffensive game. Leinster were clinical and Saracens rarely looked very dangerous. Leinster new that Saracens would really just spread it wide and not once did Saracens break away down the wing. Sexton was brilliant, I didn't expect his kicking to be so good especially just coming back from an injury that could really affect his kicking. O'brien is really showing just how phsical and mobile he really is. Heaslip was a great leader today, I also found he was really good a clearing up scrappy ball. Kearney is looking really impressive again. Horgan put in a top performance today, he rule the high ball. I think Leinsters set piece was good but I think they need to keep their disipline and I think Leinster need try and look to gain a bit more territory especially when there're trying to close out a game. None the less an away win puts Leinster at the top of the group and they are now the team to beat.
