Deila's Bhoys cruising to one big title party
Celtic 5-0 Dundee
Celtic are within 90 minutes of winning the Scottish Premiership following a comprehensive 5-0 dismantling of Dundee at Parkhead.
Leigh Griffiths' 19th goal of the season - his 15th this year - and a strike by captain Scott Brown gave the home side the interval advantage before they turned up the heat after the break.
Midfielder Kris Commons scored the third from the spot in the 71st minute then set up substitute James Forrest to make it 4-0, before midfielder Nir Bitton sealed the convincing win in style with a 30-yard thunderbolt.
The Hoops moved 11 points clear of Aberdeen with three games remaining and Ronny Deila's side will be confirmed champions if the Dons fail to beat Dundee United today.
But, should Derek McInnes' side come through at Tannadice, Celtic will travel to Pittodrie next Sunday looking to clinch their fourth successive title and, on this evidence, they will take some stopping.
Deila said: "It was a good performance. Hard to meet teams who sit in. We are starting to get used to it. We were patient and scored five beautiful goals and that makes me happy."
The 90 minutes were not open to interpretation. Celtic attacked and Dundee defended.
Celtic continued to press forward and in the 26th minute there was a more than decent penalty claim when Dundee skipper Kevin Thomson tangled with Johansen inside the box, but referee Bobby Madden was unmoved.
However, three minutes later the breakthrough arrived in simple fashion when Griffiths leapt above Dees defender Thomas Konrad to meet Emilio Izaguirre's cross and power a header past Scott Bain. The Taysiders' defence was breached again in the 37th minute with a fine team goal.
Griffiths fed Commons and he played in Brown, who barely broke stride before knocking the ball low past Bain and into the far corner of the net.
Commons missed a chance just before the break when he skied the ball over the bar from around eight yards out, but two goals looked more than enough at that point.
Celtic resumed their domination as soon as Madden signalled the start of the second half.
Dundee looked happy enough to keep the score to 2-0, but the champions-elect continued to create chances, Johansen lifting his drive from the edge of the box over the bar before Bain thwarted Mackay-Steven who had raced on to a Commons pass.
There was a double Celtic switch in the 65th minute with Johansen and Ambrose replaced by Forrest and Darnell Fisher, with the latter brought down by McGinn five minutes later for a penalty which was confidently converted by Commons.
In the 77th minute it was Commons who set up Forrest for a well-taken goal, the winger sliding in an angled shot past Bain, before Bitton slammed in number five from long range with two minutes remaining.
Attention will turn to Tannadice on Saturday but, even if Aberdeen win, the Hoops will rightly travel to the Granite City next week in confident mood.
