Arsene Wenger is clearly a fan of the Borussia Dortmund midfielder, who claims he most recently had the chance to move to London in 2012, only to join Liverpool on loan instead.
"Three times in my career I was almost at Arsenal," said the Turkey international, who opted for a six-month loan spell on Merseyside having failed to break into Real Madrid's first team. "It never happened, but that is normal in football.
"I think I was 16 the first time and then last summer we spoke with Arsenal, but in the end I signed with Liverpool."
The 25-year-old only played seven league matches under Brendan Rodgers before heading back to Dortmund in January.
But he insists he enjoyed his time with the Reds, saying: "My time at Liverpool was a good time for me, to be part of a great club with such a great history and great players.
"The club took care of me and my family; I am full of respect for Liverpool."
Sahin will come up against former Real team-mate Mesut Ozil at Emirates Stadium, and admits he is "a great player".
"He is a good friend of mine," he added. "If you said he was the only player for Arsenal it would be disrespectful, but you can definitely say he is an important part of the team."
Arsenal are leading the way in Group F having won their opening two games, while Dortmund are on three points having won and lost a game.
Sahin insists Dortmund have nothing to fear, saying: "During a game, it doesn't matter who is against you.
"It is important that we have our match plan and if we manage to have our plan and play accordingly we don't have to worry about individual match-ups."
