Coutinho is now available to return to action after being suspended for the defeat to Manchester United.
In an interview with the club's official website, Coutinho stressed that there is still all to play for and that the side can meet their objectives for the season as they are only in the early stages of the Premier League campaign and have yet to start their challenge in the domestic and European cup competitions.
He said: “We have a long season ahead and many things can happen. The Premier League is tough - all clubs have great teams - and we know twists and turns will happen.
“We have to not only remain calm but also to work hard to achieve what we want on the pitch.
“It feels bad to be out and not being available to be selected and help the team but we have to look ahead now and get over these two recent games we lost.
“There are lessons to be learned so we can move on and avoid making the same mistakes. We have a great team here and we know we can improve - and that's what we're trying to do right now.”
The Brazilian is a key player for the Reds going forward, and was missed in the defeat to Manchester United. But given the manner of the recent reversals - not just this season, but last season as well - there is a lot of pressure for improvement to be made over the coming weeks by Brendan Rodgers' side.
Thursday presents an opportunity for Liverpool to try and get an early win in the Europa League and take some control of their group, and they will hope a positive showing can help to put the two most recent poor displays behind them and allow them to kick on.
As it stands, the side is three points off the top four, which is recoverable, and have yet to get their other competitions underway, and that is probably the main message Coutinho and co will want to send out.
