"It is our best performance, especially as it comes after a couple of performances that were not up to our standards, so it means something that we beat a big club like Lazio this way," Spalletti told DAZN.
“Mertens brings that quality to the finishing, but it would be reductive just to praise him. The whole team was wonderful, it had been a long time since we had this possession football with short, quick passes.
“Zielinski found the quality within his power and technique. You'd have to really be looking for a needle in a haystack to find someone who wasn't great tonight."
There were 21 touches in the build-up to the second goal, scored by Mertens, as Spalletti concluded: “We were impeccable on the choices, on where to circulate the ball and Lazio struggled to close us down. It could've become a different game, which we saw recently when we didn't make the right decisions, but I saw great stuff tonight."
