Scotland lock Alastair Kellock believes extra competition from within the squad and the growing strength of opponents Japan mean every player in dark blue will need to be at their best at Murrayfield today.
Home head coach Scott Johnson has spoken of the need to create a deeper player pool ahead of the 2015 World Cup and lock Tim Swinson and wing Tommy Seymour make their first Scotland appearances at the national stadium. Standing in the way of the Scots are a Japan side which shocked Wales in the summer and Kellock knows the visitors cannot be taken lightly.
