Lenglet scored in the second minute for Barcelona before Kiko netted an equalizer for Valladolid in the 15th minute.
Messi, however, helped Barcelona take control with a flawless pass for Vidal before the Argentinian scored his fourth goal in four matches in all competitions and 100th under coach Valverde. A pass which only he can see sent Luis Suarez in on goal for the last one of the match. In that game, even though Messi was the dominant man, Arturo Vidal was his flawless teammate.
Barcelona were awarded a free kick and Messi made no mistake as he scored free kick number 50 of his illustrious career.
The procession was briefly halted when Ter Stegen, perhaps unsighted, slapped a cross straight into the shin of Olivas but the remaining 30 minutes of the first half belonged to Messi.
Having recorded 35 goals and a further 14 assists, the 32-year-old Argentine has been involved in 49 goals in 2019 so far, but he has another in-form striker breathing down his neck.
Messi flicked one via the legs of Oscar Plano, who threw his head again and for a second stopped useless in frustration.
Messi then set up Suarez with a well-judged through-ball, which the Uruguayan dispatched with aplomb.
"What needs to be prepared is the space for the statue, the way to pay tribute to him like [Laszlo] Kubala or Johan [Cruyff], and I've no doubt they'll find it".
Atletico Madrid could have done with a drop of Messi's attacking inspiration as they were held to a disappointing 1-1 draw by Alaves.
Gatti believes that Messi should follow Cristiano Ronaldo's footsteps and should prove himself while playing for Real Madrid.
Barca led with just two minutes played when Lenglet's strike deflected on to the crossbar and in, a kind ricochet sending the ball right to him.
