"Obviously it will be an emotional day for me, but I want everyone to know I'm still completely focused on what I see as two very important games," said the Liverpool legend.
"First I want to play well and win against Charlton to help us finish in third, and then there's preparing for and hopefully playing a part in the Champions League final.
"I'll think about everything else after that because I don't want anything to interfere with such an important match.
"I also want people to know I've not even thought about the future beyond Liverpool. The manager explained the situation to me this week and it wasn't a big surprise, to be honest.
"But everyone knows I've treated every game back at Liverpool in exactly the same way and given all I could for the team, and that's going to be the case in the last two games as well."
