Well New Zealand team is in Sri Lanka to play a short test and oneday series. Sri Lanka having the home advantage still looks quite fragile as their still in an experimental stage in terms of the team composition and captaincy. NZ eventhough whithout Mcmillan & Astle look better on paper than the SL team we Saw in Shajah recently.
Head to head Sri Lanka have been the better team by far when ODI's are considered. Their record against NZ is nothing short of phenominal having lost only 4 ODI's in the Last 20. But this could be the oppertunity for NZ to make amends.
In tests both teams look more evenly matched ... but I think the Black Caps have the edge.
