"At Liverpool, I started the season very well but once I had an offer from Dortmund in the middle of the season, I just couldn't resist the prospect of working with Jurgen Klopp again, so I decided to leave", he said, as reported by the Liverpool Echo.
Klopp, who has also offloaded Cameron Brannagan to Oxford United and sanctioned the loan exits of Marko Grujic, Ryan Kent, Corey Whelan and Matty Virtue, remained coy on any further departures amid speculation surrounding the likes of Daniel Sturridge, Simon Mignolet and Danny Ings. We played against the top of the table and played a fantastic game.
Most people aren't convinced that either of Liverpool's two main goalkeepers are good enough for the side.
Andrew Robertson produced an impressive performance at left-back and Klopp praised the Scotland's international's impact in recent weeks.
"Mo and Raggy are on the good side of it already, but with Dejan we are not 100 per cent sure [if he will be back today]". The problem they have is that everyone is watching them [through a magnifying glass] and saying 'still not good enough'.
"A lot of you (media) were in doubt about Alberto Moreno before the season and thought we needed to bring in a new full-back, which we did with Andy Robertson", added Klopp.
Much was made of the loss of Coutinho to Barcelona but the numbers being generated by his compatriot may mean the Reds move on quicker from that £142million sale than anyone anticipated.
Liverpool might have dazzled in their attacking endeavours this season in the Premier League, having smashed 54 goals in their 23 league outings but their opponents haven't found it hard to breach their defence. Fantastic goalkeeper but was he perfect? No.
"It's David v Goliath, but surprises do happen and we will be ready to prepare a surprise".
