Chelsea were beaten 1-0 at home to Leicester City on Saturday afternoon and it was a considerable setback in the Premier League.
The Blues are now only above fifth-placed Arsenal on goal difference after they were on the wrong end of an upset at Stamford Bridge.
Jamie Vardy’s second-half goal was enough for visitors Leicester to grab three points, as he latched onto a James Maddison pass in the penalty area before firing in.
Maurizio Sarri’s side did have their chances in front of goal and saw both Eden Hazard and Marcos Alonso hit the woodwork with shots.
Some Chelsea fans on Twitter vented their anger after a third league defeat of the season and singled out defender Alonso for criticism.
The 27-year-old left-back did miss a huge chance to equalise in the closing moments, while he was also given a tough match by Leicester winger Marc Albrighton.
Spaniard Alonso is an ever-present in the Blues XI at left-back, but may have teammate Emerson Palmieri pushing him for his position if supporters get their way.
Here are some of the Chelsea fan tweets on Alonso’s latest performance:
I’ve said it before. But I’ll say it again.
I’m done with Alonso. This is it.
If he was in position to actually defend Luiz wouldn’t have had to run across leaving so much space in the middle for them to score.
And don’t get me started on that miss. Yes, unlucky. But still. Wtf— ManLikeAzpi (@CFCDave_) December 22, 2018
How has Alonso gone from being the best LB in the league/Europe to one of our weakest points within a few weeks?! It’s a shame that Emerson isn’t getting more minutes. #CFC

even those clutch goals have disappeared from Alonso’s game. he is completely dross and not deserving to start over Emerson #cfc

Marcos Alonso must retire. Willian should leave Chelsea. Also if we don’t buy a striker in Jan we finish out of top 4. Simple af.

Absolutley shocking, Alonso is shocking start Emerson instead, and buy a striker that’s hungry for goal! We’re finishing 5th I’m proper disgusted!
