Ireland coach Eddie O'Sullivan believes the competition within his squad has brought out the best in number eight Anthony Foley.
The 31-year-old Munster back row has been in magnificent form for the Irish over the last year and is a key element in their 2005 RBS 6 Nations title bid.
And while OSullivan is quick to salute Foleys impressive development, he points out the 57-cap international must continue to look over his shoulder.
Anthony Foley is an experienced player. Hes worked very hard on his fitness and has always been a very good footballer, said the Ireland coach.
His experience has grown so much that at the moment hes playing better than ever, but a lot of that is because he knows he has to.
There are guys who are chomping at the bit to take his place and thats a reflection of the quality of the squad.
