On 21 July 1991, Platt moved to Italy to play in Serie A. He signed for A.S. Bari for £5.5 million and played 29 games in his first season, scoring 11 goals. In the Italian league, where goals were difficult to come by owing to the more defensive tactics adopted by most clubs, particularly for a midfielder, this was considered an impressive achievement. Unfortunately, the 1991–92 Serie A season ended in relegation for Platt and Bari.
