I think they've done it tactically.
You have a couple of players, most notably Ross Barkley, who have somehow dropped out of fashion in the PL and are thriving being big fish in a small pond. The club's achievement is getting the best out of them.
Then they have players like Doughty, Bell, Adebayo, Morris who are championship players. But their tactics have caught PL teams out. They are extremely aerial. They only things they are good at is being extremely physical and bombarding the box with quality crosses and causing chaos.
But PL teams are not used to those tactics. I thought PL teams would adapt to this much quicker, but they haven't. It's catching them out constantly. Luton concede the sort of goals you would expect a shit relegation team to; but they are scoring far more because of this aerial bombardment and chaos making.
Essentially, they have done a Wimbledon. And it may well keep them up at our expense.
I actually think it could keep them up again as well. PL sides just aren't adapting and if they could get PL quality in their back three, they could establish themselves.
The problem would be in being able to pick up PL quality players who can do what they want them to. Top class players don't really play that way. You need pickups from the football league and that's much harder
This is not really how Luton play.
Only a small example, but Morris ran around lots of the Bournemouth players and curled a shot onto the post.
Clark dribbled through the middle of the park.
Bit of a scramble on the edge of their box, and he slipped one in the far side of their goal.
The winner, was a whipped/low cross, that Morris out-muscled their defender to score.
Hardly some hoofball, "Wimbledon style" aerial assault.
Perhaps its Bournemouth, and they just suit the way Luton operate; but look at their goals in the 4-3...not one where they were overly physical, just slick passing and precise movements leading to quality goals.
So, in actuality, selling their style to higher quality, but similar, players is probably hampered by their name and the amount they could shell out in wages or amortisation, rather than the project.
Their limitation, much like ours, is their defence. They'll have no problems scoring goals - and good quality goals at that - but keeping them will be their achilles heel.
Whatever, its going to be a lot closer than some think here.
