The 2011 CONCACAF Under-17 Football Championship was the 15th edition of the CONCACAF Under-17 Football Championship, a tournament for national teams of countries from North and Central America. None of the candidate host countries has already hosted one of the previous editions of the European Football Championship for women. Mertens started the game as a bench seat, but was allowed to fill in for Marek Hamsik in the last half hour. In the end, he only got 17 starting places in the league and was allowed to come on 14 times. At the end of the season, Mertens started to become more important to the team with four starts and three goals. In the fall of 2013, Mertens seemed to find his way with the Italians with three basic places in a row. Mertens signed a 5-year contract with the Italian top club, where he went to play under the new Spanish coach Rafael Benítez. During the summer of 2015, Mertens was explicitly linked with a transfer to Internazionale, where he should succeed Xherdan Shaqiri, who has left for Stoke. On June 24, 2013, it was announced that Napoli had paid 9.5 million euros to take over Mertens from PSV, a relatively low amount given his performance in Eindhoven (for comparison: Strootman left for AS Roma for double that summer).

With another 12 assists, Mertens had a solid share in Napoli's third place. This article describes the achievements of the Italian football club AC Milan in the 1993/94 season, in which the club won the UEFA Champions League and won the national title for the third time in a row. Finally, Totò scored in the game against England for third and fourth place. In all competitions together, he scored 18 times for the "lamp club" that season, making him less productive than his first season in Eindhoven. ↑ Summary: FC Eindhoven – FC Volendam. ↑ Emanuele Giaccherini (Juventus) debut for Italy. ↑ Jean-Éric Vergne drove the fastest lap, but as he did not finish in the top 10, the point for the fastest lap was awarded to Daniel Abt. On January 6, 2014, he scored two goals in one game for the first time against Sampdoria, a match won 2-0. He scored the second goal on March 30, 2014 in the 2-0 win against league leaders Juventus. On September 30, 2013, Mertens scored again 3 times in the 0-6 victory at VVV-Venlo. He then also provided two assists in the 5–1 win. In his two seasons at PSV, Mertens was a basic player.

At PSV, Mertens grew into a very productive player in two seasons, who was important in terms of both goals scored and assists. After two seasons, the new set-up turned out to have had a counterproductive effect on the level, appearance and public interest. In the cup competition, Mertens was important with two goals in four games. In the entire cup competition he was important with three goals in five games. In the 2012/13 season, Mertens was again important for PSV. The club has very limited financial resources and this is reflected in the organization: players have to set up and take down the equipment for training sessions, have to wash their own uniforms and polish their own football boots. On August 5, 2012, PSV won the Johan Cruijff Shield (Dutch Super Cup) against Ajax 4–2. Mertens played the full game, provided an assist for the first goal, but did not score himself. He scored the decisive 1-2 that brought in the three points. The backlog at a safe place in the rankings had become nine points. It was remarkable that Mertens hardly played entire matches.

He scored three goals in 11 European games. He made an appearance in 88 official matches.

When he scored this goal in a duel with goalkeeper Remko Pasveer, he lost two front teeth. On the last matchday he scored twice against Hellas Verona. On matchday ten, on October 30, 2013, he scored his first goal for Napoli in Serie A against Fiorentina.
