Atletico Madrid striker Diego Forlan has labelled Chelsea as the 'best team in the Premier League'.
The Uruguayan hit-man is set to go head-to-head with the Blues in the latest round of UEFA Champions League fixtures on Wednesday.
A tricky trip to Stamford Bridge is the last thing the Spaniards need, though, with only one point taken from their two European outings so far and their league form still alarmingly erratic.
Forlan, who spent two years in England with Manchester United between 2002 and 2004, admits Atletico will face a mammoth task upon their arrival in London.
He feels Chelsea are now the dominant force in English football, with the experience within their ranks and the tactical nous possessed by coach Carlo Ancelotti edging them above reigning Premier League champions United.
"Chelsea have more quality, are more experienced and are a much bigger threat than they were in my time at United," Forlan said in the Daily Mirror.
"They lost at the weekend (against Aston Villa), but, for me, they are the best team in the Premier League. With the arrival of Ancelotti, he has made them stronger in defence and more dangerous going forward.
"Ancelotti has really motivated players like (Didier) Drogba, (Michael) Ballack and (Nicolas) Anelka. The absence of Drogba for the Champions League makes it difficult for them and is good for us.
"But we are prepared for Stamford Bridge and we know we can cause an upset and hopefully I can score. I always get a reaction from the English supporters but that only inspires me."
