Goals from Erling Haaland, Phil Foden and Julian Alvarez helped Manchester City seal a dramatic 3-2 comeback victory over RB Leipzig in the Champions League.

Lois Openda's stunning brace had given the German side a shock lead at the break before Pep Guardiola's men produced a stirring comeback to seal top spot in Group G.

Here are five talking points from an entertaining night at the Etihad.

Cause for celebration

Before a ball had even been kicked, those present at the Etihad were treated to a spectacle of a different kind.

A dazzling lights show accompanied a moving video tribute to the trio of Mike Summerbee, Colin Bell and Francis Lee — the stars of City's 1968 title-winning side who had a statue unveiled in their honour earlier in the day. 

Clips of the trio's best moments graced the big screen to the delight of the home crowd, who proudly belted out the names of their heroes of yesteryear. 

While City's current era have scaled unthinkable heights, it was warming to see the club give a nod to their less illustrious past.

Carved Open

If this fixture was supposed to be an uneventful clash between two already qualified teams, nobody briefed Leipzig forward Openda.

The blistering Belgian, 23, ran rings around the City backline from the first whistle, with his deceptive strength and breathtaking pace proving too hot to handle for the shell-shocked hosts.

His first goal saw him effortlessly brush off Manuel Akanji on halfway before coolly slotting past Ederson — with the sluggish Ruben Dias suffering the exact same fate 20 minutes later.

Thankfully for the Portuguese defender, his torrid evening was cut short when Guardiola saw fit to haul him off at half-time and bring on Nathan Ake.

Sloppy City

Guardiola's team selection suggested the Treble winners were taking this game very seriously but their first-half showing said otherwise.

Though Openda's showing deserves great credit, City's defence fell well short of their usual standards and were bypassed far too easily on numerous occasions.

Further up the pitch, passes were being uncharacteristically misplaced while any chances being carved out were being spurned — even by the mighty Haaland.

Guardiola cut a frustrated figure throughout the opening period and a reaction felt somewhat inevitable.

Phil your boots

Alvarez and Jeremy Doku entered the fray on 55 minutes and City kickstarted their comeback second later — though it was Foden who played the starring role.

The Englishman's delightful through ball was taken in by Haaland, who resumed normal service with clinical low finish to become the youngest ever player to net 40 Champions League goals.

Foden then levelled matters himself 15 minutes later when brilliantly controlling a Josko Gvardiol pass before deftly sliding the ball beyond Janis Blaswich.

And there was no prizes for guessing who assisted the winner on 87 minutes when the Stockport-born star's low pass deflected into the path of Alvarez, who finished with aplomb.

Strength in depth

Even when two goals down and looking well out of sorts, a turnaround always felt somewhat inevitable, which speaks volumes about the levels this City side possess.

One goal was always going to bring a second and a third, with Leipzig visibly wilting under the relentless pressure applied by the hosts' array of attacking jewels. 

To see the magnificent Doku and prolific Alvarez arrive in a double switch must have had opposition boss Marco Rose shaking his head in disbelief.

That terrifying squad depth is the leading reason why it will be so difficult to dethrone them as European champions.
