Arsene Wenger is clearly a fan of the 25-year-old 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."
