Jurgen Klopp admitted he switched his tactics two or three times during their goalless draw against West Brom, but believes they had chances to win.
Klopp restored Firmino and Coutinho to the lineup and started with a 4-4-2 formation, which he later switched to a 4-3-3 during the match.
Klopp agreed he changed tactics during the game and it might have affected the dynamics, but saw chances of winning.
“First half we were a little bit stiff, the passing and movement was not so good but even then we had two or three chances,” said Klopp.
“The second half we changed the system two or three times. It was difficult but I think only one time Loris Karius had to make a save – an important one.
“We can do better and we have to do better but on a night like this when you are not at your best you need a bit of luck.
“That was not our best game but I think we had enough chances to win. We didn’t use them and we have to accept the result.”
