Jurgen Klopp believes his current Liverpool squad is the strongest he has ever had as a manager.
Liverpool are third in the Premier League table, and hold a 5-0 first-leg lead over Porto in the Champions League last-16.
Klopp has used 28 players in all competitions this season, relying on rotation to balance their prospects in two competitions.
Though the German has won the Bundesliga title and reached the Champions League final with Borussia Dortmund, he says he has “never had a situation” where he is leaving such talented players out of his squad each week.
“It’s really hard in the moment to make the squad; we’ve had a few players not in the squad,” he told Liverpoolfc.com.
“Wow, I’ve never had a situation like that with the quality of the players not being in the squad.
“They all have made really big steps. Dom Solanke was not in the squad but is in outstanding shape at the moment. Ragnar Klavan, unbelievable. Ben Woodburn makes steps and is really close to everything.
“It’s difficult, it’s getting more and more difficult, but that’s good – very good – for us of course.
“Danny [Ings] made it, he came on. It was a high result but it was not about that, it was only because he deserved it and we wanted to give Roberto a little bit of rest, so Danny came on and it was nice to see.
“He enjoyed it a lot, worked hard, was quick and adapted immediately to the game, so it was a really nice story.”
