Stuart Lancaster admits selection headache

England head coach Stuart Lancaster has admitted that he faces a selection dilemma ahead of the side's first Test match against Argentina on Saturday.

The Red Rose put in a strong performance on Sunday with a 41-21 victory over the CONSUR XV in Montevideo.

The boss concedes that the display has given him plenty to ponder ahead of his side's series with the Pumas.

"There are decisions to be made in the make-up of the back row and the bench," said Lancaster. "As you can see from the game, the breakdown will be fiercely contested on Saturday and there were times when we didn't deliver as good ball as we wanted.

"I have some decisions to make as to how we go about the game. The most important thing for me is it makes it clear how difficult it will be next Saturday.

"The sessions will be fiercely contested. We need to prepare well on Tuesday in order to get our mindset right for Saturday."

Lancaster will name his team for the clash with Argentina on Thursday.
