The race to become Scottish champions next year is already very much underway.
While Rangers have aspirations of kicking on next term and providing viable competition, the target at Parkhead is much more ambitious.
Coming away as Champions next term will mean that Celtic have made in 10 titles in a row - something that their rivals will certainly find difficult to stomach.
However if the Bhoys are to do that then they'll need to make sure that they make a success of the summer's transfer market.
That means bringing in some real quality, something which is definitely on the radar.
According to reports in The Sun, Celtic are keen on a move for Grady Diangana.
The West Ham winger is currently on loan at West Brom where he has been in stunning form so far this term.
The Baggies are on track to secure promotion to the Premier League, with Diangana likely to be a summer target.
However with Celtic now on the scene, it seems that a move could be a little bit more complicated than first thought.
The 22-year-old is said to be valued at around £20million, meaning that any move would be a significant outlay for the Scottish champions.
GIVEMESPORT'S Phil Spencer says...
Grady Diangana is likely to be in high demand this summer.
After being so impressive for West Brom this term, it seems that he's destined for a move to a higher level.
Celtic and West Brom are said to be keen, and there's no doubt that he'd be a real asset to both sides.
£20m is a significant fee, but if he can show some of the impressive form that he has in the Championship this term, it could be money well spent.
However it remains to be seen whether West Ham would be willing to let him go at all.
