Quique Setien may want a different Barcelona but he needed the same old Lionel Messi on Sunday as the Argentinian gave his new coach a winning start by scoring in a 1-0 victory over Granada.

Messi’s strike in the 76th minute decided a cagey contest at the Camp Nou and prevented the much-anticipated launch of Setien’s new era becoming something of a damp squib.

Victory also sends Barca back to the top of La Liga on goal difference, after Madrid had briefly claimed first place following their win over Sevilla on Saturday.

 I already saw some of them against Atletico (last weekend) because Barca has been doing great things for many years.” It would have been different if Granada’s Yan Eteki hadn’t struck the post with just over 20 minutes left or their central defender German Sanchez not been sent off for a needless second yellow card soon after.

The extra man was the boost Barca needed and Messi duly poked home his 17th goal in 21 games this season following good work by Arturo Vidal, Antoine Griezmann and the 20-year-old Riqui Puig.

All three had reasons to impress, particularly Puig, whose inclusion on the bench was an early indication of Setien’s belief in youth. Puig's contribution after coming on should mean more opportunities are to come.

Setien said last week that if he could make one guarantee, it was that Barca would play good football while he is in charge and although few could argue this was a transformative display following the sacking of Ernesto Valverde, there were certainly some encouraging signs.
