Jurgen Klopp has "found his right midfield" in recent weeks according to former Liverpool player and Sky Sports pundit Jamie Carragher.
Much of that has been down to Jordan Henderson's position further up the field, where the skipper is able to make runs into the box and support the attack.
Klopp also insisted that Naby Keita's performances in training were of such a high calibre that he couldn't possibly leave the Guinean out in the last three games.
The duo, alongside the ever-present Fabinho, have formed a solid partnership in the middle of the park and Carragher believes Klopp has found his best midfield at a pivotal time of the season.
"At a vital time of the season, Klopp has almost fell upon a midfield in some ways because it wasn't his idea to play Henderson (in an attacking role)," he said on Sky.
"Henderson got himself in that position because of his performance coming off from the bench in that position that night.
"The midfield balance is great now, Henderson's getting in the box and he was again brilliant against Porto in midweek.
"Maybe, just at the right time, Jurgen Klopp has actually found his right midfield."
Liverpool take a 2-0 lead to Porto in the Champions League quarter-final second-leg on Wednesday night.
