Patrick Roberts' loan spell at Celtic has been a pretty fantastic success for all parties concerned so far. Fourteen months have passed since he arrived in Glasgow looking for a more significant taste of first team football than what he'd been used to in his career up to that point.

Initially providing a much needed creative boost to Ronny Deila's side, he's continued his development under Brendan Rodgers who is one of the best managers he could currently be working with on a day to day basis.

Not only that but he's won winners medals, played in the UEFA Champions League, become a hit with supporters and forged a brilliant friendship with Kieran Tierney!

The young winger is set to return to Manchester City this summer but we reckon the Hoops should be going all out to gain his permanent signature, even if it costs a fair wedge of cash.

Here are five reasons why...

He can score goals like this

Patrick Roberts possesses one of those natural and effortless goalscoring abilities, the kind that the opposition must hate because no matter how they try to combat it, players like Roberts can produce magic from almost any situation.

In the video above he receives the ball on the halfway line and less than 10 seconds later it's in the back of the net. Yes you could argue Aberdeen gave him far too much room and you'd be right, but you can't argue about the finish, a truly sumptuous drive into the top corner.

If Celtic did invest in Roberts, supporters would likely see this on a regular basis.

He can turn it on at the highest level

There was a lot of pressure and spotlight on Patrick Roberts' shoulders when Celtic went to the Etihad last December in the final game on the UEFA Champions League group stages. It was arguably a game that meant more to him than any other person in the stadium given that final positions in the table had been decided already.

He turned it on in a big way and scored a lovely goal against his parent club showing that not only can he produce quality at the highest level but that he could do it with a bit of pressure on him.

Celtic are hoping to have another tilt at the group stages of the competition next season so need the kind of quality that Roberts possesses to try and be competitive. In a tough market, attracting familiar faces may be easier than convincing others.

It would allow Rodgers to make him the main man

While the form of James Forrest has undoubtedly been very good in spells this season, you get the impression that if Roberts were not leaving at the end of the season that Brendan Rodgers would perhaps be more willing to commit to the young Englishman.

There's no sense in playing him every week at the expense of the likes of Forrest, who has just committed to the club with a new contract. We're sure Rodgers picks the best XI available to him every week but it would be more justifiable to give Roberts more of a shot were he a permanent player.

Having the club invest in him heavily could allow Rodgers to make him the main man on the right wing, knowing that his development and future will always benefit Celtic in the long run. Combined with Scott Sinclair on the left it would be a very formidable wing set-up at the club.

 Seven assists, despite limited starts

Kieran Tierney and James Forrest are leading the way in the Celtic assist charts with 8 each but they've played many more games than Patrick Roberts, who has just one less on 7. That's pretty impressive and highlights his creative skills are second to none at the club.

If he can add more goals to his game he could be approaching the kind of impact that Scott Sinclair has had on the side who, while actually assisting less that Roberts with 6, has scored a massive 17 goals for the club this season.

That kind of assisting rate from Roberts will be hard to replace and could even end up costing Celtic close to what it might take for the young on-loan star to move to Celtic Park permanently.

Re-sale value

We've seen Celtic's transfer model used to great effect in recent years with the likes of Virgil van Dijk, Fraser Forster, Ki Sung-Yeung and Victor Wanyama all moved on for big profit after good spells at the club. The same could be true for Patrick Roberts even if the winger costs a little bit more than those players did initially.

At just 20 years of age he has the whole world ahead of him if he continues learning and working as hard as he has done up to this point.

A couple of more seasons at Celtic, permanent ones, could really be the next stage in his career that he's looking for. Just look at how Moussa Dembele as his enhanced his reputation in the game this season.

If Celtic show commitment and willingness to invest and nurture his talent then he could follow a similar path to his former Fulham teammate and that can only be a positive for both the club and the player.
