I've read this from quite a few posters here ... people say they cannot see any system and everything comes down to individual brilliance, basically there’s no tactics coached.
But I think there clearly is, the difficulty is that because of injuries to key players, Ole has had to adapt his ideas throughout the season, though I would suggest that this shows even more tactical nous from him.
At the beginning of the season Ole wanted to build around Pogba in the 4-2-3-1 formation that he used in Norway and obviously favours. The team would press high and play with a high defence stealing the ball back early and playing quick forward passes from between the lines onto runners like Martial, James, Lingard and Rashford. The key to this was the other midfielder (McT, Matic or Fred) dropping back in between the CBs allowing the FBs to push forward either into midfield to protect against a counter or into attack to become another option for the pass forward, so effectively 4-2-3-1 would switch to 3-2-5 in attack. Pogba was key to this as he was the creative force meant to be spraying the ball about the pitch, but Pogba got injured and there was no one else in the squad to fill that role.
So he had to adapt to working with a much more utilitarian midfield. Liverpool do this by using their full backs as the creative force, but AWB wasn’t bought for this and though Shaw is capable it’s not his strongest suit either. But Ole didn’t have a huge amount of choice as the need for creativity moved out of central midfield and onto the wings, more often than not the left side with Shaw and Rashford. It still involved midfielders dropping into defence, but this now it meant a holding midfielder (often Fred) dropping into cover either LB or RB depending on who was pushing forward. With Martial, Shaw and Rashford all out at different times as well this became increasingly difficult. We all know how that worked out. Though he certainly had some successes, Tottenham and City stand out, but so do Newcastle and Norwich.
Finally with the purchase of Bruno, Ole got what he’d been missing with Pogba out, a playmaker to operate between the lines. So once again he could switch the creativity back to midfield, push Rashford and James/Greenwood out wide with Martial running through the centre. The other midfielder could drop back to create a back 3 and the wingbacks could either tuck in to protect midfield or push up to support the attack. Yes Bruno played in a more advanced position than Ole had planned for Pogba, but the idea pretty much remained the same with the idea of 4-2-3-1 switching to 3-2-5 in attack again.
These ideas aren't completely original, Ole has borrowed a bit from Klopp and Pep (who obviously play quite differently anyway) as well as others. He’s been forced to adapt throughout the season and you could argue that his tactics didn’t really finally click until that fecking Brighton game when you hammered us after lockdown (it was that game that got me thinking and reading about this)
He has also made mistakes as he and his coaches are quite inexperienced at this level, though I don’t mean he can not succeed and clearly the players don't think that either as they seem totally bought into his ideas. So to say there is no system is wrong in my mind, there has been at least three clear systems throughout the season (that's not counting the odd time he's started with 3 at the back or 4-4-2, which is another post all by itself!) as he’s adapted to the players available. Now whether you think the tactics are good enough or not is another discussion enitirely!
Interesting analysis written by cleverer people than me here.

tl:dr – Ole actually does have a clear system, but it has changed through the season to adapt to injuries. Saying there is no system is wrong!
