Kieran Tierney delivered when it mattered most as Celtic opened their title defence with a win over Dundee. The left-back proved his worth in a contest that showed why Brendan Rodgers kept faith in him despite injury concerns heading into the season.

Tierney's performance went beyond typical fullback duties. He provided defensive solidity down the flank while contributing in the attacking third, the kind of two-way play Celtic need if they're holding onto the Premiership. For a player who's dealt with fitness issues, getting through ninety minutes clean and sharp matters. It signals he's ready for a long campaign.

This wasn't Celtic dominating a minnow and cruising home. Dundee pressed, created problems, and made them work for it. That Tierney held up his end against sustained pressure tells you he's not just available for the easy fixtures. The Hoops need depth and form from their wing-backs if Rangers push them in the months ahead.

One win doesn't define a title race. But Celtic showed they're serious about defending what they won last year, and Tierney's display suggests they've got the personnel to do it. That's worth noting heading into the business end of the season.
