Manager Brendan Rodgers warned there will be "more days like this along the way" while rebuilding Liverpool after his side crashed to a 3-0 loss at West Brom to open the Barclays Premier League season on Saturday.
In addition, defender Daniel Agger was sent off for a professional foul when conceding the first of two spot-kicks awarded to the Baggies.
Only poor finishing prevented West Brom from doubling their tally while at the other end of the pitch Liverpool striker Luis Suarez spurned two golden opportunities.
"There is a big job to do and we will have more days like this along the way," Rodgers said. "That is the reality of it. It is still a work in progress. There will be days along the way that will hurt and it will be difficult for us. It is going to take time. Hopefully we won't have too many days like that and we will keep moving forward."
Rodgers knows his side have to be more clinical in front of goal and Suarez, for all his brilliant approach play, needs to increase his conversion rate of chances.
"The reality of the situation is we need to score more goals," Rodgers said. "If we are going to affect the top of this league, we have got to score more goals."
"I like Phil. He is normally a good ref for me. We are not going to get everything our way," Rodgers said. "A couple of harsh decisions went against us, we never scored our chances and West Brom took full advantage of the extra man. "But the players have been brilliant since I came here and gave everything at West Brom. They ran themselves to a standstill."
Rodgers admitted to being concerned over the recurrence of substitute Joe Cole's hamstring injury which led to him being taken off.
"It is strange because Joe had trained all preseason very well and then got injured in our first European game with Gomel," Rodgers said. "He came back, did well in training, came on at Albion for 10-15 minutes and the hamstring has happened again. It is something the medical people will have to look at."
