"Liverpool are unbeaten in their seven previous European ties with Porto and I expect them to win in the Estadio de Dragao although it is unlikely to be as emphatic a scoreline as last season's last 16 tie when the Reds romped to a 5-0 success", Owen told BetVictor.

"His fitness levels are getting better and better", he said.
