Jürgen Klopp believes FC Porto will sense 'an opportunity' to avenge last season's Champions League elimination at the hands of Liverpool tonight, but feels Anfield can give his side an edge in the first leg of the quarter-final tie.
The Reds defeated the Portuguese champions 5-0 at the Estadio do Dragao in the initial meeting of the last-16 encounter last term, before a goalless draw in the return on Merseyside assured safe passage into the next stage of the competition.
However, the manager feels Porto will use the memories of that experience as a catalyst to try to 'strike back' this time around.
