Romelu Lukaku emerged from the Inter Milan bench to score a crucial winner against 10-man FC Porto in their UEFA Champions League round-of-16 first-leg clash.
Lautaro Martínez and Hakan Çalhanoğlu still had chances for the hosts with a miscued header and a cheeky effort at the near post, but the best opportunities came towards the end of the half.
Porto fired the first warning shot as Marko Grujić paid the price for choosing power over precision from close range, seeing his low strike saved before Galeno headed the rebound off target.
