3) Celtic – 216 Wins
The Hoops last featured in the group stages of the Champions League back in 2013/14 but the fact that they are regular winners of the Scottish Premiership means they have participated in the qualifying rounds.
Celtic did win the old European Cup all the way back in 1967, and also reached the final for a second time in 1970, so it is not a surprise they are so high up on this list of British teams.
