Chelsea twice came from behind to scupper 10-man Wrexham's hopes of a giant-killing in a thrilling FA Cup fifth-round tie in Wales.

The eight‑time winners were set on their way to the quarter-finals thanks to Alejandro Garnacho's extra-time volley that put them ahead for the first time, with substitute Joao Pedro wrapping up the win late on.

Victory came after the Premier League side had struggled for much of the contest when 11 versus 11, in front of the Welsh club's Hollywood owners Ryan Reynolds and Rob McElhenney.

It was a dramatic tie, with Sam Smith squeezing a shot in at the near post after exploiting Chelsea's high line to open the scoring for Wrexham.

But winger Garnacho forced an unfortunate own goal before half‑time when his effort was cleared by George Thomason onto Wrexham goalkeeper Arthur Okonkwo's back and rebounded into the net.

The second half was end to end. Chelsea made a series of changes after a poor opening 45 minutes, but Wrexham went back in front when Josh Windass' edge‑of‑the‑box half-volley was cleverly flicked in by standout performer Callum Doyle.

Their elation lasted only four minutes, however, as Josh Acheampong drilled a powerful shot inside the near post to restore parity for Chelsea, with winger Pedro Neto blasting a powerful effort against the bar moments later.

The turning point, however, came after an intervention from the video assistant referee (VAR) and an on-field review of the video monitor by referee Peter Bankes, who sent off midfielder George Dobson for a high and forceful foul on Garnacho in the 93rd minute.

In extra time, Wrexham began to tire and faced shots from Andrey Santos and substitute Marc Guiu before Garnacho was left free at the back post to side foot home Dario Essugo's clipped cross.

A dramatic 114th-minute equaliser by substitute Lewis Brunt was ruled out by VAR for offside but highlighted how Wrexham threatened late on through further shots through Kieffer Moore and Windass.

It was a shaky showing from Chelsea but Joao Pedro added gloss to the scoreline by catching a tired Wrexham side on the counter‑attack to make it four just before the full‑time whistle.

Chelsea avoided defeat against lower league opposition for the 25th consecutive match in the FA Cup and reached the quarter-final having not won the competition since 2019.

Wrexham manager Phil Parkinson spoke of this match being a chance to celebrate how far the club have come.

After all, while these days there might only be 20 places between the teams in the pyramid, it was only three years ago that Wrexham were having to play in the FA Cup's qualifying rounds.

They certainly made the most of the occasion, with the pre-match tribute to club icon Joey Jones - also fondly remembered by Chelsea fans for his promotion-winning time at Stamford Bridge - a classy touch to set the tone.

Indeed, the atmosphere had the clenched fist feel of the Welsh great's trademark salute, while on the pitch, players carried his fearless nature.

But Wrexham have not found themselves in the Championship play-off positions on attitude and spirit alone.

Parkinson does not get enough credit for his ability to get tactics spot on for the different challenges Wrexham have faced in their recent rise, switching between pragmatism and taking the game to opponents.

They did that here, growing in confidence as fans gained belief.

Sensing the opportunity, they pressed higher and added to Chelsea's uncertainty.

And the quality possessed by the squad Parkinson has cleverly assembled was none more so displayed by the wonderful flick from Doyle.

It was a moment that allowed the old ground to dream, before Chelsea's moments of quality that handed them the advantage in extra time.

Perhaps Wrexham should not have been surprised that cameras would have a say in their story as VAR played the villain, with Chelsea's players happy to play a supporting role as they saw the game out.

But while there was no Hollywood moment for the on-watching owners, there are perhaps more significant fixtures to come this week with the play-off hopefuls facing fifth-placed Hull City on Tuesday before a Welsh derby with Swansea City on Friday.

Neither extra time nor Dobson's red - with injury problems already an issue in midfield - will have been welcome to Wrexham.

But on a night that was a chance to reflect on how far Wrexham have come, it only added to the anticipation of what could yet follow.

You would not have known which side had been a non‑league outfit just two and a half years ago from watching the first 45 minutes.

Chelsea made nine changes, leaving Cole Palmer, Moises Caicedo and Enzo Fernandez out entirely, with Cucurella, Reece James and Joao Pedro among the substitutes.

On the pitch, Chelsea started with five defenders, two defensive midfielders and only three natural attackers - and it showed.

They did not register an attacking action of note until defender Jorrel Hato, playing out of position as an attacking midfielder, floated a poor cross into the arms of the Wrexham goalkeeper.

Garnacho took 27 minutes to produce Chelsea's first shot, tame as it was, while the equaliser in the 40th minute came firmly against the run of play.

It was a far cry from the quality on display at Aston Villa in midweek, as Chelsea tried - and failed - to rotate their squad effectively.

It leaves the question of whether Chelsea underestimated Wrexham with Paris St‑Germain looming in the Champions League, or whether their second string simply falls well short of the level required.

Of course, the quality from the bench eventually told, while Dobson's red card took the wind out of the Championship club's sails despite them coming close to equalising in the second half of extra time.

Questions remain for Rosenior - who is encouraged by the hierarchy to rotate - and about Chelsea's wider approach.

Should they really be averaging five changes per match, avoiding the use of the same back four in consecutive games since appointing their new manager, or even rotating their goalkeepers Robert Sanchez and Filip Jorgensen at this stage?

Wrexham host fellow promotion-chasers Hull City on Tuesday (19:45 GMT) and Welsh rivals Swansea on Friday (20:00 GMT) in the Championship.

Chelsea next play away at Paris St-Germain on Wednesday (20:00 GMT) in the last-16 of the Champions League. They return to Premier League action when Newcastle visit Stamford Bridge on Saturday (17:30 GMT)
