The Liverpool icon was full of praise for one centre-back but defended his criticism of another.
An Eden Hazard penalty opened the scoring for the visitors at Anfield, before Raheem Sterling equalised in the second half, leaving the Capital One Cup semi-final perfectly poised heading into the second leg at Stamford Bridge.
And Carragher has praised centre-back Sakho for his contribution - as well as his form since returning to the Liverpool side.
'@samps64 Agree, Sakho's problem is he looks awkward but his passing & defending have been very good since he came back in the team.— Jamie Carragher (@Carra23) January 20, 2015
According to data from WhoScored.com, Sakho enjoyed a fine night for Liverpool statistically, winning five aerial duels, two interceptions and making five clearances, as well as achieving a 91.2 per cent passing accuracy - although the Frenchman won no tackles.
Another Liverpool centre-back on the night, however, was the subject of criticism from Carragher for his display against Chelsea.
And the Reds icon defended that criticism after the game. The man in question, of course, is 21-year-old Emre Can.
'@RBreed Why?He got caught out twice for the penalty incident,very good on the ball but against Leicester & Wimbledon also he found it hard.— Jamie Carragher (@Carra23) January 20, 2015
Interestingly, Can made six tackles according to the stats, while he enjoyed a better second half - especially on the ball. It was the German who committed the foul for Chelsea's penalty, though, and that kind of error needs to be cut out with experience.
