Celtic beat Dundee United 3-0 on Sunday - here are five things we learned about the Bhoys.
Bitton - now a key player?
Earlier this season, Israeli international midfielder Nir Bitton was a bit-part figure, struggling to break into the Celtic midfielder on a regular basis. Now, he's a fixture of the side under Ronny Deila and was outstanding against Dundee United, providing a shield for the defence and using possession superbly. The 23-year-old has proven his worth, and looks like being a star of the future for the Bhoys.
Not getting the best out of Armstrong
January signing Stuart Armstrong returned to face former club Dundee United, but didn't have the best of returns to Tannadice. The midfielder was hauled off after an hour and replaced by another former Terror in Gary Mackay-Steven, with Armstrong struggling to get involved in the game. Asked to come in from the flanks and contribute, Armstrong isn't really the type of player to take on the opposition and would rather create from the centre of the park - hence his lack of involvement. Getting the best out of the January arrival is something to consider for Deila.
First half lethargy
Celtic were superb in the second half, but it came after a terrible first half where they struggled to get the ball moving at any real tempo and didn't trouble Dundee United enough. The final ball was lacking and we've generally come to expect better from Celtic under Deila. The introduction of Mackay-Steven certainly helped with his direct running and pace, so maybe Deila needs to play him often to give some balance to the Celtic side in the final third.
Griffiths - Celtic's most improved player?
The aforementioned Bitton would be in contention for this particular accolade, but Griffiths' improvement in the second half of the season has been remarkable. After just four goals in the first half of the season, Griffiths has now his 14 in the second half, with his second hat-trick in 11 days. Clearly Celtic's best striker right now, the 24-year-old is thriving under Deila - and long may it continue after another impressive display.
Edging ever closer
We've assumed it for some time now, but Celtic are finally close to being crowned Scottish Premiership champions for a fourth successive season. The 3-0 win at Tannadice means Deila is close to claiming the title in his first season in charge, and whilst that is exactly what is expected of any Celtic manager, we've seen Celtic develop into a different type of team under Deila, playing a high pressing game, and whilst there have been some growing pains at times, ending the season with two trophies will be a fine way to finish Deila's debut season in Scotland.
