Thibaut Courtois has called on his Chelsea team-mates to fight back against Manchester United on Sunday, live on Sky Sports, following their 3-0 Champions League defeat at Roma.
El Shaarawy scored twice against Courtois on Tuesday, before Diego Perotti sealed Roma’s win in the 63rd minute.
Chelsea have kept only one clean sheet in all competitions since September and head coach Antonio Conte urged his side to “dig deeper” following their defeat in Rome.
Chelsea welcome Jose Mourinho’s side to Stamford Bridge on Sunday and Courtois called on his side to improve, saying: “It is hard to say what the problem is. This season every game is a hard game.
“Sometimes last season I had nothing to do in a game, sometimes I’d have one save to make. We have to react on Sunday as this was a bad image of ourselves.
“We have to find that balance again and rediscover that mentality of not conceding goals and keeping clean sheets.
‘We have to fight back against Manchester United.”
