Luciano Spalletti told his Inter team to stay grounded after a sixth straight Serie A win lifted the Nerazzurri to second in the table.
Mauro Icardi scored a brace in Monday's 3-0 win away to Lazio, with Marcelo Brozovic also on target at a wet Stadio Olimpico.
Inter moved within six points of leaders Juventus, who are seeking an eighth straight league title as their domestic dominance looks set to continue.
And Spalletti, who has stated Inter's aim is to qualify for the Champions League, will not get carried away with his side's fine form.
"The performance is the fundamental thing," Spalletti said to Sky Sport Italia.
