Another new era begins at Barcelona with the appointment of Quique Setién. 

The 61-year-old was nowhere to be seen amongst the favourites but it is he, not Ronald Koeman, Xavi or Mauricio Pochettino who replaces Ernesto Valverde at the helm. 

The former Las Palmas and Real Betis coach inherits a Barca side top of La Liga, but under immense pressure to win the Champions League. 

Of course, he also inherits the means to do so and go one better than Valverde.

Setien is now the guardian of Lionel Messi. 

The Argentine pulled his former coach over the line countless times, even attracting his team the unwelcome nickname of 'Messi FC'. 

However, the accusation that Barcelona have over-relied on their six-time Ballon d'Or winner predates Valverde. 

It was even thrown at much more popular coaches like Pep Guardiola, who has often had to contend with the suggestion that he would never have won the Champions League without his talisman - especially as he's failed to repeat the feat with Bayern Munich or Manchester City. 

With that in mind, Planet Football have provided a breakdown of Messi's goals and assists under various managers since Guardiola. 

We've gone back a step and looked at his record since his debut in 2004 and included his individual and team honours for good measure.

Messi paid tribute to Valverde in his latest Instagram post thanking him for his work in Catalonia. 

The two did appear to have a great relationship, but it was undoubtedly under Guardiola that Messi was at his very peak.
