The Brazilian stole the headlines with the winning goal as Liverpool edged Manchester City 3-2 in a thriller to take control of the Premier League title race
The Brazilian pounced on a scuffed clearance from Manchester City captain Vincent Kompany on the edge of the box to strike an instinctive first-time finish past a despairing Joe Hart with the game tied at 2-2, emerging as the match-winner in a pivotal clash in the title race.
The win at Anfield saw the Reds stay top of the table, two ahead of Chelsea and seven ahead of City with four games left, although the latter have two games in hand. But the result put Liverpool firmly in control of their own destiny, with the title now theirs to lose.
And Coutinho was a crucial factor in the win, showing he was well up for the game straight from kick-off with a couple of crunching challenges on Samir Nasri and Gael Clichy. The attacker was always involved in the Reds attack and his sleight of feet caused trouble for the City players, along with fellow team-mates Luis Suarez and Raheem Sterling.
City were gaining the momentum having come rallied from a two-goal deficit at half-time to draw level but Coutinho's goal effectively killed it, coming as it did in the 78th minute.
The composure and technique from Coutinho to hit the ball for his goal, as well as the awareness to react quickest, may yet prove to be his most vital contribution this season. If Liverpool do go on to win the league, their number 10 would have played a huge role with this particular goal.
