Celtic defender enters war of words with Rangers

Celtic defender Mark Wilson has hit back at outgoing Rangers manager Walter Smith's comments suggesting the Hoops were the catalysts for a controversy-filled season for questioning the authority of match officials.

Smith's final game in charge at Ibrox was last Sunday's 5-1 win over Kilmarnock which secured the Clydesdale Bank Premier League title for Rangers by one point from Old Firm rivals Celtic.
