MIDDLESBROUGH, England (Reuters) -Chelsea suffered a surprise 1-0 loss at second-tier Middlesbrough in the first leg of their League Cup semi-final on Tuesday with Hayden Hackney's goal giving Mauricio Pochettino's wasteful side plenty to do in the return.

The 21-year-old Hackney's silky finish from an Isaiah Jones pass stunned the visitors in the 37th minute at the Riverside Stadium and the hosts defended superbly to take a slender advantage to Stamford Bridge.
