Jurgen Klopp said Liverpool “were not smart enough” in some areas of their game, as they were frustrated by Everton.
Liverpool were unable to return from the three-month break with a win, as their rivals Everton held them to a goalless draw.
While the result was frustrating for Klopp’s side, they still just need five points to confirm their first league title in 30 years.
Liverpool had been in rampant form in the months leading up to the postponement of the league, but weren’t quite at their top gear for their first game back.
The circumstances upon the return were rather different, which Klopp admitted – although he was impressed with the intensity of the derby, even without fans present.
Klopp told Sky Sports: “It was a real fight. Both teams showed they understand it is a derby. Intense, physical, all players were all in.
“We didn’t have enough chances. Most of the time we were dominant but they had the biggest chance.
“Everton defended really well and we were not smart enough to use the space. That is normal when you start to play again.
“Football looks slightly different, but I take that.”
