Chris Boden takes a look at Burnley's 1-0 defeat to Swansea City on Saturday
Ahead of the game, midfielder David Jones spoke of the lessons Burnley needed to learn from the last experience of the Premier League.
Jones felt, two seasons ago, it was too often a case of, good performance, but the wrong result.
Calling for the Clarets to be more ruthless, he said: "Results are the main priority. We need to learn from our mistakes last time. I felt we played a lot of good games but we didn't come away with any points and that's what we want to try and improve on this time.”
However, Burnley, who delivered a season-long masterclass in gaining results when not at their best in the Championship, again fell into the trap of delivering a good display, but coming away empty-handed in the top flight.
While that is clearly something Burnley will have to develop going forward, and quickly, there are other aspects of Premier League life they have to acclimatise to.
Sean Dyche made his feelings known after the game, after seeing a string of incidents where Swansea players, particularly their widemen, enhanced or simulated contact to gain an advantage.
Mo Barrow and substitute Jefferson Montero, in particular, went to ground, blatantly to the naked eye, without being touched, and won free kicks.
Burnley discovered two years ago, fair play gets you nowhere in this league. Curiously, the last time Swansea were at Turf Moor, Sam Vokes drew criticism from pundit Ruud Gullit for being honest and not going to ground in the area under a challenge from Neil Taylor.
Jon Moss was the referee who failed to spot a foul that day.
On Saturday, Moss was again in charge, and he again failed to spot Michael Keane being prevented from heading Burnley in from by a clear shirt pull from Leroy Fer.
Fer should have been sent off, and a penalty awarded. To add insult to injury, Fer, who shouldn't have been on the pitch, scored the Swans' late winner.
Welcome back to the Premier League. Early in the day, a so-called elite official gave a hugely debatable penalty in favour of champions Leicester. That decision didn't alter the outcome of that particular game, but the standard of officiating already leaves much to be desired.
While we're on the subject of learning lessons, while Sean Dyche's side gave absolutely everything for the cause, it's clear they need some support in terms of competition.
The board of directors are to be admired for their prudent approach in times of, frankly, immoral transfer fees, and clubs leaking money like a sieve.
But they need to remove the financial straitjacket Dyche is working with. Steven Defour would be a start.
Yes, the club have tried to spend money over the summer, having multi-million pound bids turned down for a string of players, while turning down eye-watering sums for Michael Keane.
With just over a couple of weeks to go before the transfer window closes, the club desperately need to strengthen Dyche's hand, or risk suffering the same fate in their previous two Premier League campaigns - glorious failure.
The back five is relatively young, has Premier League experience and quality. The front two will be a threat. But the midfield - as the summer transfer sagas suggest - is in need of reinforcements.
Dean Marney was the pick of the players on Saturday, picking up where he left off at this level before his cruciate injury. What a difference he would have made two seasons ago from February onwards.
And Jones has been a superb servant, with his metronomic passing and pressing.
That ball manipulator remains elusive though. That extra bit of craft and guile - that which could also bring an extra dimension from Andre Gray, who looks lean and hungry to take his chance in the Premier League.
More pace out wide would also be welcome. One only has to look at Barrow, Montero and Wayne Routledge's threat on Saturday - pace that didn't come at a huge cost. Routledge cost £1.75m, Barrow around £1.5m, and Montero for £4m.
