Jurgen Klopp must decide whether to stick or twist on £36m transfer mistake

“It’s a huge game for Porto and they have got in once or twice,” Owen told BT Sport during their first-half analysis.

“Konate worries me a little bit, I must say.

“He presses a little bit, he comes in and likes to mark men and a lot of the time he gets done in behind.

“A couple of times there, we missed one or two off the reel we could’ve shown where people are getting in behind him so I think they’ve just got to be careful without [Virgil] Van Dijk there.

“Communication might be key between them. They don’t strike me as two players, Matip and Konate, that are going to speak to each other much.

“They’ve looked a little bit vulnerable. They need to tighten that up.”
