On Saturday we host Sheffield United in the Premier League for just the fifth time, but how much can you remember about our previous matches against them at Stamford Bridge in this competition?
With this being only the Blades' fifth campaign in the Premier League and our not having met in cup competition until just before that competition started in 1992, we have only hosted them at the Bridge four times in the Premier League previously.
Those matches have always produced at least three goals but fairly mixed results, with two Chelsea wins, one draw and one victory for the visitors, although that was back in the Premier League's first season in 1992/93. How well do you remember what else happened in those four games between Chelsea and Sheffield United at the Bridge? Find out in our quiz below, and good luck!
