Totti's years under Zdeněk Zeman represented a period of both physical and mental maturation as a player. From a technical and tactical standpoint, he proved to be compatible on the left wing in the rigid formations of the Bohemian coach, as his new role gave him more space to take on defenders in one on one situations, and cut into the centre to shoot on goal with his stronger foot; he also became physically more powerful, fit, hard-working, and complete. He displayed a greater responsibility for the team, and was presented with the number 10 jersey. His first season under Zeman started well, with Totti taking advantage of a 4–3–3 formation and making his breakthrough with the club. He finished the league season reaching double figures in goals scored for the first time in his career; including a goal in the club's 2–0 away win against Napoli on 22 February 1998, Totti scored 13 goals in Serie A in total, and contributed to Roma's fourth place league finish that year.&lt;ref name="Italy Championship 1997/98"&gt;&lt;/ref&gt; Although he was not called up for the 1998 FIFA World Cup by Italy manager Cesare Maldini, his consistent performances, creativity and goalscoring throughout the course of the previous Serie A season saw him being awarded the Guerin d'Oro for the 1997–98 season, given to him for having achieved the highest average rating of any Serie A player. The following season, he began to gain recognition as a club symbol and as a leader, and on 31 October 1998, Totti became the official team captain, and the youngest Serie A club captain ever at the age of 22, inheriting the armband from Aldair. On 29 November 1998, Totti scored the equalising goal in a 3–3 draw against cross-city rivals Lazio; this was his first ever goal in the Rome Derby. Overall, he scored 30 goals and provided 26 assists during Zeman's two-year managerial stint. For his performances, he was named the Serie A Young Footballer of the Year for the 1998–99 season.
