A 5TH ROUND clash at Luton looms for Chelsea after Plymouth Argyle were squeezed aside at Stamford Bridge in the FA Cup.

At one stage a giant-killing looked possible, and it was only the new-found penalty-saving confidence of keeper Kepa that ended the Pilgrims’ progress.

In extra time (with the score at 1-1 after Argyle took the lead with a glancing header after eight minutes, and the Blues replied via a Cesar Azpilicueta backheel just before the break) Chelsea edged in front with a Marcos Alonso shot.

Then Plymouth sub Ryan Hardie won, and took, a penalty… only to see it saved.

The prospect of a trip to Kenilworth Road will stir uneasy memories among fans of a certain age.

Back in the 1980s it was the scene of street-fighting between rival gangs of supporters, and the wanton smashing of shop windows en route to the railway station at the end of the match.

For several seasons afterwards, Chelsea fans taunted visitors to the Bridge with the chant: “You’ll get the same as Luton.”

The sides met this time last year in the cup, with Chelsea winning 3-1 thanks to a Tammy Abraham hat-trick – a bizarre game in which Timo Werner missed a penalty.

Werner was, frankly, awful against Plymouth after coming on as a late sub in normal time. He bottled a clear chance to take a shot as a white-shirted opponent was running towards him.

It’s surely only a matter of time before Tom Tuchel loses patience with the German who is still cheered by home fans.
