Jurgan Klopp has held meetings with Liverpool's players to warn them against falling into the traps Atletico Madrid will set to disrupt them.
Liverpool's manager withdrew Sadio Mane at half-time in the first leg of the last 16 tie as he was concerned the Senegal forward would end up reacting to heavy treatment and receive a red card.
Atletico's players kept surrounding referee Szymon Marciniak that evening, asking for him to take action against Mane, and Klopp expects there will be similar pressure applied as the Spaniards, who are holding a 1-0 lead, attempt to knock the reigning champions out.
