Celtic one away for six in a row
Dundee 1 Celtic 2
Celtic are within one victory of a sixth successive title - they can secure it against Hearts at Tynecastle on April 2 - after a win that had to be ground out against a stubborn Dundee side at Dens Park.
Jozo Simunovic sent the runaway league leaders en route to extending their unbeaten domestic run to 36 matches with a shot on the bounce from a first-half stoppage-time corner kick, although his effort went in off the back of Kevin Gomis.
There was no ambiguity about Celtic's second six minutes after the break.
A fine, flowing move released James Forrest on the right and his precise cross was met with an equally clinical header by Stuart Armstrong.
For a spell, there were signs that Dundee might crumble - as so many others have done during this campaign. Paul Hartley, however, responded with commendable ambition by making three attack-minded substitutions.
The last switch yielded reward almost immediately when, with 15 minutes left, French-Moroccan striker Faissal El Bakhtaoui ran straight at the heart of the Celtic back line and uncorked a 25-yard drive which lanced beyond Craig Gordon.
Dundee might have retrieved a draw when Marcus Haber found space to meet a cross at a favourable angle near the back post, but could only glance his header off target and the Dark Blues were left to rue a third single-goal defeat by Celtic this season. © Daily Telegraph.
