Jamie Redknapp believes Tottenham have given Chelsea serious reason to be worried.
Jamie Redknapp believes Chelsea's away form must come under the microscope after they were swept aside by Tottenham at White Hart Lane.
Spurs defeated them 5-3 despite going a goal down, and it was the first time a Jose Mourinho Chelsea side has ever conceded that many.
The former Liverpool and Tottenham midfielder told The Mail: "Harry Kane was unplayable and he terrorised a top defence. His work-rate inspires his team-mates and he is the difference for Spurs.
"For Mauricio Pochettino, it’s a great confidence boost. He looks like he could be the right man for the job and Spurs fans will be looking forward to seeing what he can achieve with the right investment.
"For Jose, it’s a huge blow. This was a shock and their away form is a real problem."
Chelsea are joint top of the league with Manchester City with exactly the same number of points, goals scored and conceded.
Away from home they have gained four less points than City - but their record is still the second best in the entire Premier League, picking up two more points on their travels than Spurs.
Chelsea's two defeats this season have both come away from home, but overall it's hard to agree with Redknapp it's a trend Mourinho must be concerned about, instead specific areas of their woeful defending at White Hart Lane must take sharper focus.
