Coutinho's absence from the Liverpool squad has only fueled speculation continuing to circulate around his future, with Barcelona long-term admirers of the midfielder, who is seen as an ideal replacement for the recently departed Neymar.
Coutinho was keen to leave Liverpool in the summer and join Barcelona and even handed in a transfer request.
Coutinho missed the Reds' last 3 fixtures, a pair of Premier League games versus Huddersfield and West Ham, along with a Champions League matchup with Maribor, after picking up a thigh problem.
Barcelona are reportedly ready to return for the attacker, but Coutinho has insisted that he is happy with Liverpool and at the moment, has no desire to leave the club.
But he has declared himself fit for Brazil's clash with England on Tuesday night at Wembley.
"I think my game is suited to it because I'm fast and I know how to use my strength".
Liverpool Superstar Suffers Another Injury During International Break
Sadio Mane has returned to Liverpool from global duty after Senegal confirmed he has aggravated his hamstring injury. Before that match, the winger's hamstring issue had kept him out for the previous five matches.
But Coutinho has been in full training since Thursday and says he is fit to face England, "Unfortunately, I could not play for Liverpool in the past three games because of injury". I am honoured to wear this shirt whenever I can.
"I'm always happy. But now it's important to concentrate on the national team".
"The team was happy when he was back", Klopp said in September.
"Every day, I work harder than before to improve myself and become a better all-around footballer", he concluded. "We are looking forward to competing against them", he said.
As for Liverpool, while they sometimes struggle to convert their chances into goals-they've failed to win six of their 11 Premier League games this season-their attacking play is similarly exciting to watch when everything clicks in an impressive collective effort. "Football has been very generous for me".
