Messi, a guaranteed goal getter for new coaches

The Camp Nou will see this Sunday a very special match since it will be the beginning of the Quique Setien era on the Barca bench. 

The fans are eagerly awaiting a clash in which the manager will be looking to win over the fans through the team's play. 

There are high expectation and nerves as well, but Setien will be able to rely on a player who always scores when a new manager takes over: Leo Messi. 

The Argentine will once again lead Barca on the pitch and Setien will be hoping he scores again. 

The '10' has become a specialist in scoring easily every time a coach has taken over on the Barca bench. 

Messi missed Guardiola's opening game in charge, a Champions League qualifier, but he found the back of the net twice on Tito Vilanova's debut, a 5-1 victory over Real Sociedad. 

In the 2013-14 season, Tata Martino's first Barca match was a 7-0 win over Levante and Messi got a brace in that fixture.

Messi got two in a 3-0 win against Elche in Luis Enrique's first match in August 2014.

Finally, Messi scored Barca's only goal in Ernesto Valverde's first Barca fixture. However, the Catalans went on to lose that game 1-3 to Real Madrid in the Spanish Super Cup first leg.
