Four-midable Celts stretch lead
Partick Thistle 1 Celtic 4
Stuart Armstrong grabbed a double as relentless Celtic moved 11 points clear at the top of the Ladbrokes Premiership with a comfortable 4-1 win over Partick Thistle at Firhill.
The former Dundee United midfielder opened the scoring in the 39th minute to give an otherwise dull first half a notable end.
The champions came out flying at the start of the second-half and notched two goals in a minute from Armstrong and returning striker Leigh Griffiths and although Jags defender Liam Lindsay reduced the deficit with a header just after the hour mark, Hoops substitute Callum McGregor restored their cushion for Brendan Rodgers' side who still have two games in hand over second-placed Rangers
For a game that Celtic were odds-on to win, Rodgers made three changes to the side which started in the 1-1 Champions League draw with Manchester City on Tuesday night.
Defender Cristian Gamboa, winger Gary Mackay-Steven and striker Leigh Griffiths came in for Jozo Simunovic, James Forrest and Moussa Dembele, the latter starting on the bench.
Thistle also looked solid enough defensively in the early stages although in the 23rd minute Jags keeper Tomas Cerny had to make a fine save from Griffiths' low drive after winger Patrick Roberts had set him up with a cut-back.
Moments later, the Scotland attacker drove wide from 25 years with an effort which was as unconvincing as the visitors' play.
However, it was Leigh Griffiths who became provider in the 39th minute when he got past right-back Ziggy Gordon and drove the ball across the six-yard box and past Cerny for on-rushing midfielder Armstrong to slam into the net for his fifth of the season.
Armstrong's second four minutes after the restart was a finish of real quality as he accepted a free-kick from Griffiths before curling a left-footed shot from 25 yards past Cerny and into the far corner.
The visiting fans were still celebrating when Griffiths took a pass from Rogic, rolled Thistle defender Adam Barton with some ease before lifting his shot high into the net.
When Lindsay, making his 50th appearance for Thistle, looped a header from a Sean Welsh free-kick over Gordon, a comeback was hinted at.
In the 81st minute left-back Emilio Izaguirre reached the bye-line before sitting his cross up for McGregor, on for Rogic, to volley in number four and keep Celtic unbeaten in the league - they have dropped two points - and inexorably on way to their sixth successive title.
