As one of the most well supported clubs in Europe, it is perhaps no surprise that some of the continent’s most highly rated talents have played for Celtic over the last decade or so.
Celtic’s recruitment strategy of sharpening up some of the world’s top young talents and selling them on at a big profit has proven extremely successful for both the club and the players, meaning you can find several of the Hoops’ former star players featuring in elite leagues such as the English Premier League, the Bundesliga and Ligue 1.
