Technically, it's 10 years and 343 days, because his never-ending run started on 1 November 2006, when CSKA Moscow managed a 0-0 draw with Arsenal.
Since then, Akinfeev has played in 42 Champions League matches in goal for the Russian side, and he has conceded at least once in every single one of those games. An infamous record which, luckily for him, doesn't bother the Russian goalkeeper.
When CSKA travel to Switzerland to play Basil, it will be the last opportunity for the 31-year-old to get the coveted clean sheet before his run reaches 11 years. 1 November of this year will be the anniversary of the match which, at the time, no one thought would be particularly special.
