Brazil forward Coutinho has called for his Liverpool teammates to keep their focus in order to achieve the club's "big objectives" this season.
The 24-year-old recently returned from an ankle injury and came on in the 61st minute in the 1-1 draw on Sunday away to Manchester United at Old Trafford.
Despite taking a lead through a James Milner penalty, United managed a late equaliser through Zlatan Ibrahimovic.
Coutinho reckons his team need to rediscover their form to curb a four-game winless streak ahead of Wednesday's FA Cup clash against Plymouth Argyle.
