The Brazilian playmaker remains a prime target for the La Liga giants when the transfer window reopens in just over six weeks' time and hopes remain high at the Nou Camp that they can finally tempt Liverpool into selling the player.
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 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'm always happy. But now it's important to concentrate on the national team. I am honored to wear this shirt whenever I can".
"England will be out first European opponent under [coach] Tite. We are looking forward to battling with them", Coutinho said.
The Mirror claim that Liverpool were unhappy when the 25-year-old chose to join up with his national squad when he required treatment for a thigh injury.
"I'm always a happy person but right now, my focus is exclusively on the national team and once the match is over, then it will be Liverpool. It will no doubt be a hard encounter", he added.
"The team was happy when he was back", Klopp said in September.
