Ghana striker Majeed Waris made his Champions League bow on Tuesday night for Porto who suffered an embarrassing 5-0 defeat at the hands of Liverpool at home.
Waris was brought on in the 62nd minute but he appeared powerless on the field to stop his side from the hands of the free-scoring English side.
Sadio Mane and Mohammed Salah combined to produce all five goals for Liverpool. Mane hit a hattrick while Salah scored a double. Liverpool will expect to complete the job when they host Porto in the return leg at Anfield on Tuesday, 6 March.
The Ghana international joined Porto from Lorient in January. He has made four appearances so far but is yet to find the net.
