Brendan Rodgers insisted his side's performance deserved much more than the 2-1 defeat they suffered to Manchester United at Anfield on Sunday as he confirmed injuries to Daniel Agger and Fabio Borini will require further assessment.
Borini was replaced by Suso at half-time after picking up an ankle injury, while Agger was carried from the field with 10 minutes remaining after sustaining a knock to his knee.
Rodgers told his post-match press conference: "Fabio had a badly swollen ankle and was struggling to put any sort of force on the floor, so we'll assess that tomorrow and see how he is. It looked badly bruised at half-time.
"Daniel Agger we'll need to wait and see. It didn't look so good with his knee, and some of the medics were saying he may have a problem with his medial ligament, but we'll to assess that over the next 24 hours and look at it again tomorrow."
Liverpool dominated the contest for long periods, but were dealt a blow when they were reduced to 10 men shortly before half-time after Jonjo Shelvey was shown a red card following a challenge with visiting defender Jonny Evans.
Nonetheless, Steven Gerrard fired the Reds into the lead shortly after the interval before full-back Rafael levelled up the game with a curling effort.
United were then awarded a penalty with 14 minutes remaining after Glen Johnson was adjudged to have fouled Antonio Valencia in the box, which was converted by Robin van Persie.
"I'm bitterly disappointed with the result - I thought the best team lost," Rodgers told his post-match press conference.
"What we could control, I thought the players and the performance level was outstanding. What you can't control is decisions by the referee.
"We're bitterly disappointed it didn't go our way today, but performance wise I thought the players were outstanding.
"We dominated the majority of the game, even with 10 men, but it didn't go our way."
Rodgers was left disappointed by refereeing decisions that saw Shelvey sent off, Antonio Valencia win a penalty for United and Luis Suarez denied a spot-kick after he went down under a challenge from Jonny Evans with the scoreline tied at 1-1.
On the red card, the manager said: "If Jonjo Shelvey gets sent off, Jonny Evans has to get sent off. If you watch the replays, if Jonjo's got sent off for both feet leaving the ground, then Jonny Evans has to get sent off for that as well.
"It's a tackle a player has to go for. It's also a tackle the Manchester United player has to go for - but the Liverpool player can't get sent off for it and the Manchester United player stay on the field.
"I thought it was a very, very harsh decision and throughout the game that's how it went for us. A number of decisions went against us and that [the sending off] ended up costing us the game."
He continued: "I think everyone will see it was never a penalty. Glen Johnson has made a fantastic recovery run back in and I don't know why Valencia goes down. It was certainly never a penalty. Then, at the other end, Luis Suarez gets a toe to the ball looking to go around the defender, he gets the contact, goes down and doesn't get a penalty.
"The only help we got today was from the crowd, who were absolutely phenomenal right the way through the game and I think they respect and appreciate what we're trying to do.
"Decisions didn't go our way, for sure."
The result means Liverpool are still awaiting their first Barclays Premier League win under Rodgers - but the boss remains confident his team are heading in the right direction after a performance from which many positives can be derived.
He said: "I remember Arsenal last year didn't get off to a great start. I think performance wise, everyone can see the growth in the group. There are a lot of young players looking to define a style of play. I think we're seeing that and seeing some a lot of positive moments in the games, particularly over the last couple of weeks.
"There has definitely been growth and I've got great confidence. Very, very soon our luck will change and we'll do what it takes to win games - and when we do, I believe we'll fly."
One such positive was the performance of Spanish teenager Suso, who replaced the injured Fabio Borini at half-time and turned in an impressive display on his first appearance in the Barclays Premier League.
"Fabio goes off and young Suso came on and I think you could see the excitement," said Rodgers. "There are a group of young players here who hopefully in the next few years can take the club forward.
"We'll have to wait and see with the injuries, but on the other hand the positives are some young players are getting an opportunity and doing very well."
Before the game, Anfield paid its respects to the 96 people who lost their lives at Hillsborough in the first home game since the release of the Independent Panel's report.
United also paid tribute, with both sets of players wearing jackets with 96 printed on the back and Old Trafford ambassador Sir Bobby Charlton presenting Ian Rush with a bouquet of flowers to lay at the memorial.
"This was my first involvement in a game of this magnitude and it was a privilege and a pleasure to manage the club," said Rodgers. "The work Ian Ayre has done to organise the tributes has been fantastic.
"As I said before the game, we are two leading and iconic clubs and we have an obligation - morally and socially - to show we can respect and I felt that was done today."
"There is an intense rivalry here, and you don't want that to end because that's a part of what makes this the biggest game in British football."
