Connacht are the Pro12's Leicester City. A year ago no one would have predicted they'd be title contenders but, with five rounds left to go, they are top of the table. Leinster are only a single point behind, so tonight could determine who goes on to finish at the head of the league.
Both teams will have their internationals backs, which should benefit Leinster more than it does Connacht. This could provide an opportunity to see Robbie Henshaw face off against his future teams, if he is included in the match day squad.
After losing last week, Leinster will be determined to get the win, and have the experience and talent to do it. Connacht have the home advantage, and will not want to slip up this close to a potential semi-final. A tough fight is guaranteed.
