Porto manager Sergio Conceicao expects to face a more alert Chelsea side on Wednesday after the Blues surprisingly lost to Premier League relegation battlers West Brom at the weekend.
Chelsea took an early lead against the Baggies, but a Thiago Silva red card turned the tide at Stamford Bridge and the Blues would eventually go down 5-2 in Thomas Tuchel's first defeat as the club's manager.
Conceicao admitted he would have preferred Chelsea to win that game ahead of his side's Champions League quarter-final first leg on Wednesday.
