Summer signing Mika Baur notched his first goal for Celtic as the Scottish champions maintained their perfect start to their William Hill Premiership title defence with a 1-0 victory away to St Johnstone.

The German midfielder struck from close range early in the second half after debutant Hoops keeper Sam Johnstone had produced a stunning first-half save to deny Saints midfielder Joel Cotterill.
