GLASGOW WARRIORS coach Franco Smith is remaining grounded despite seeing his side open the Champions Cup pool stage with an impressive six-try, bonus-point win over Sale Sharks.

George Horne was the star man as the Scotland scrum-half notched a hat-trick of tries in a 38-19 win against the Premiership side at Scotstoun.

Smith, though, warned against any premature celebrations with just one match played so far in a potentially long campaign.
