Hugh Farrelly of the Irish Independent selects his Overseas XV currently plying their trade in Ireland - and casts his eye back over the hits and the flops.
"If 2009 was Rocky's year, then 2010 belonged to Isa. When it comes to overseas signings leaving an impact on Irish rugby, then Rocky Elsom's contribution over the course of one glorious Heineken Cup-winning season with Leinster will be nigh on impossible to top.

"However one feels about an out-and-out Australian declaring for Scotland and then playing his club rugby in France and Ireland, there is no doubting Hines' commitment to whatever team he togs out for, and his physicality and experience were invaluable in Leinster's recent back-to-back clashes with Clermont.
