How do you improve upon an almost perfect season? That's what this campaign has been for Brendan Rodgers and his Bhoys. Celtic are on the verge of an unbeaten domestic season and a rare domestic treble of trophies. It would be unprecedented in the history of the game in Scotland.

They've triumphed against all challengers in all situations. They've blitzed teams, they've narrowly won hard fought encounters, they've survived scare draws and they've come from behind to win matches too.

Celtic fans had high expectations of Rodgers' reign in Glasgow but few could have predicted just quite amazing it's turned out to be.

Still now though, the ceiling is high, he's not taken them as far as they can go, he's not made supporters as happy as they can be.

These are the four things Rodgers could improve upon next season to take supporters higher and higher...

Win at home in Europe

One of the key aims next season will be improvement in Europe and it all needs to start with much better performances at home in the UEFA Champions League. Assuming they make it past the summer qualifiers again, supporters will be hoping the team can be more competitive in front of sell-out crowds at Celtic Park.

Outclassed by both Barcelona and Borussia Monchengladbach, it was only against Manchester City they truly shone and they still did not do enough to secure a win.

Three points at home is probably the minimum supporters will expect next term as Brendan Rodgers aims to build a team not just capable of dominating domestically but also going up against the best sides Europe has to offer.

If the Hoops start to put the pieces together in Europe as well as at home, supporters will be as happy as they've ever been, certainly in decades.

A Rangers whitewash

Celtic have enjoyed significant derby dominance over Rangers this season. There were two 5-1 wins, two cup semi-final wins and two wins at Ibrox. It's a quite sensational record in a derby that has regularly been competitive.

The is one small tiny thorn in that record though and it's the 1-1 draw at Celtic Park in March. It's a game Celtic should have won, Rangers were without a permanent manager after all.

For whatever reason the Hoops just couldn't put together performance required to get over the line in that one and despite a joyous season, it leaves a key aim left next term.

Whitewashing Rangers and winning every match would be humiliating for supporters of the Ibrox side and give the Hoops bragging rights for years and years to come.

What better way to follow up an exceptional season against them than to go one better next time around?

Europe after Christmas

If Celtic do manage to have an upswing in their home European form, the ambition must be to ensure they see European football after Christmas. Whether that is in the UEFA Champions League by finishing second in the groups or in the UEFA Europa League by finishing third probably doesn't matter too much.

In fact the Europa League might be a happy hunting ground for Brendan Rodgers' men. We've seen this year that teams like Ajax can go deep into the competition, a team that last season didn't look too far ahead of the Hoops themselves.

If they can ensure knockout football after Christmas then this side have the spirit, belief and the backing of 60,000 fans that make them a formidable foe for most sides in Europe.

Can Brendan Rodgers emulate the success of Martin O'Neill and deliver some famous European nights into 2018?

Young blood

What's better than being incredibly successful in football? Being incredibly successful with homegrown talent. There's nothing Celtic supporters enjoy seeing more than players of their own, from their own communities reaching the pinnacle of Scottish and European football.

Just look at how popular players like Kieran Tierney are.

The Hoops have some decent talent almost ready to make their first team bow. Jack Aitchison, Michael Johnston, Anthony Ralston and Calvin Miller are all knocking on the door. Bringing in this new wave of youth could be a significant story at Celtic Park this season.

If Brendan Rodgers manages to not only oversee a brilliant Celtic team, but one with genuine homegrown talent, his popularity will sky rocket even further.
