Former Barcelona captain Ronald Koeman has slammed Chelsea after their victory over his old club last week.

The Feyenoord coach was unimpressed by Chelsea's tactics for the 1-0 Champions League semifinal first-leg win.

Koeman said: "As a coach, I could never let my team play like Chelsea did against Barcelona."

Didier ­Drogba's goal, from Chelsea's one strike on target, gives the Blues something to defend in the Nou Camp on Tuesday.

Koeman added: "I watched Chelsea defend for 90 minutes and I was appalled they did not try to make something more of the game. I have no admiration for Chelsea's approach.

"And, let's face it, this tie could have been all over by now. ­Barcelona could easily have won in London.

"Let's hope football will be the winner this week and the team with the best approach goes to the final.

"It is the moment when a team like Chelsea have the chance to create something and they won't which annoys me. As a team, you can't sit back and wait for Barcelona all the time."
