Arsenal legend, Paul Merson, has highlighted a major problem for Chelsea.
The Blues suffered a shocking 1-0 defeat to Nottingham Forest at home on Saturday.
Former Manchester United star, Anthony Elanga netted the only goal as Forest ran out 1-0 winners at Stamford Bridge.
The defeat means that Mauricio Pochettino’s Chelsea have won just one of their four games.
Merson watched the game for Sky Sports and said: “It happened again today, they never looked like scoring a goal.
“It’s disappointing. I think they’ll be alright away from home, when teams have a go, because of Nicolas Jackson and Raheem Sterling’s pace.
“This has been happening for a couple of years now, trying to break teams down. Against Liverpool they were really good because Liverpool came out and played, but when teams come and sit with 10 men behind the ball…
“Luton did it last week. Chelsea scored after 10 minutes and you thought it was going to be a cricket score.
“But for the next 30-50 minutes, it was slow, the fans were getting frustrated. Mauricio Pochettino’s job is to get this team up and really pressing.”
