"We could have scored the first goal with [Sam] Byram, we should have equalised and the third goal was a unusual decision", said the Hammers boss.
Adam Lallana feels Liverpool passed a major test of character in the race for a Champions League spot by thrashing West Ham on Sunday.
"IT was a very hard season, a very long one".
Sunday's game against West Ham was the flawless kind of game for Liverpool to lose.
The 24-year-old was in brilliant form as he scored twice and assisted a goal in the 4-0 demolition of West Ham which put Liverpool one step closer to a place in next season's Champions League.
This season Coutinho has most often lined up on the left of Liverpool's three-man attack.

Yet two more goals from Neymar put the result beyond doubt in the sun-drenched Canary Islands. Zidane says his players are committed to Real's key fixtures remaining in this campaign.
Coutinho turns 25 this summer and is entering into his prime years as a footballer, and now seems like a turning point in his career with a more central role ahead.
Marked less tightly and with space, Coutinho made his presence felt from the outset and it was his delicious defence-splitting pass on 35 minutes that opened the scoring for Liverpool.
Sturridge, making his first Premier League start since January, slotted the visitors into a first-half lead before Andre Ayew somehow hit the post from two yards with the goal at his mercy. He struggled a little bit in the last few weeks with different parts of his body.
You'll struggle to find a better individual display in the Premier League this season than Philippe Coutinho's against West Ham. He needs to be in the decisive area in the middle of the park, he needs to be in shooting situations and all that stuff.
The Hammers goalkeeper also had to be alert to keep out James Milner's low drive before watching Coutinho's long-range effort drift just over the top of his crossbar.
West Ham, who beat second-placed Tottenham Hotspur in the previous round, have struggled at London Stadium this season since their shift from Upton Park, but Reid was confident they can improve next term. Barcelona's advances will remain strong but the message from Anfield needs to be straightforward: our main man is going nowhere.
