Speaking ahead of Sunday's return to league action, Leinster coach Michael Cheika said: "There are some very big games coming up over the next three weeks in the context of retaining the Magners League title.
"The derby nature of the next two games (against Ulster and Munster), as well as the European qualification (against Harlequins). It's going to be in an interesting combination of which players play and when.
"Obviously if you look at Ulster they have a few players like (Rory) Best, Paddy Wallace and Tom Court who will all be returning from the Irish team. It's a big test for us.
"I think that Ulster will be buoyed by their win against Munster at Thomond Park and they will definitely be targeting that 'away double.'
"We got two very good results away in Wales and everybody's excited about getting back to playing regularly again.
"You can feel the energy and enthusiasm in training and I'd like to think that we have improved a little bit over that time.
"We know that our title aspirations are in the next two games, but all that we can manage is our result against Ulster."
