Barcelona vs. Sevilla...where do you even start?
One of the truly great European games was a rip-roarer of a contest from the moment Ever Banega slotted the underdogs ahead after three minutes.
Neither manager will be happy with the quality, or lack of it, with regards to defence and perhaps the same can be put down to some ring-rustiness.

The reality is there is no excuse for some of the elementary mistakes that were being made time and again but it was an absorbing contest for the neutral.
Let's take a look at three things we learnt.
Pedro still worthy
The rumours surrounding Pedro Rodriguez moving to pastures new won't go away and the player himself refused to rule it out.
BBC report that after the game the player noted when asked if he wanted to leave.
He said: "The answer is no. But it is a difficult, complicated situation. When you know you may leave it is difficult.
"I've not said what Robert's [Robert Fernandez, Barcelona Technical Secretary] said, or at least not how I said it.
"The truth is that I had a good chance to play. The coach has decided not to count on me. I don't know, I don't know if I will continue here."
Regardless, the player showed his absolute worth to the club by poaching the winner, coincidentally in the same minute as he did in this competition against Shakhtar Donetsk in 2009.
He was lively, first to every ball and that his first contribution was to receive a yellow card showed his determination to get involved.
For all of Barca's protestations that they want the player to remain, lowering his buyout clause from €150m to just €30m was always going to invite bids. To then suggest that any move is of the player's own doing is a little disingenuous on the club's part.
Main man Messi
Although Lionel Messi was largely anonymous in the latter part of the game when Sevilla mounted a fightback that deserved better than they ultimately received, his two free kicks in the space of the opening quarter-hour were of the highest quality.
They gave Barca the platform to take the game to their opponents who had taken a shock lead just two minutes in.
Messi was unplayable in the first 45 minutes and was once more the fulcrum to any good work from the Blaugrana.
Neymar was sorely missed in the end, but Messi showed enough alongside Suarez to give everyone a nudge that he'll be right back in amongst it this season.
What does Unai Emery have to do to win against Barcelona?
This was somewhere in the region of his 20th attempt with different clubs and his bogey team still managed to take the plaudits and the trophy despite one of the great football come backs.
Emery has his teams player in the right way and a sign of his sheer excellence in the role is that despite having to sell their best players again during the summer, a studious buying policy and acumen of the manager has meant barely any drop off in quality and a work ethic that will see the Andalusians challenging at the top table once more.
The manager can take a lot of heart and pride in his teams' performance, and it's surely only a matter of time before Emery will break his duck against the Blaugrana.
