4. Thierry Henry – Juventus to Arsenal – £11m
A lot was expected of Henry when he joined Juventus as a youngster, however, he failed to establish himself in the first team and generally disappointed on the wing before Wenger saw the potential in him as a striker. One relatively small transfer fee later and Arsenal were equipped with one of the finest, classiest striker’s that the Premier League has ever known. He overtook Ian Wright to become the club’s all-time leading goalscorer before being sold on to Barcelona at the age of 30 for a massive €24m.
