Simone Inzaghi says Inter's "destiny is in our hands" after a 3-1 victory over Sheriff moved them up to second in Champions League Group D.
Marcelo Brozovic, Milan Skriniar and Alexis Sanchez were on target for the Serie A side at the Bolshaya Sportivnaya Arena, while Adama Traore scored a late consolation for the hosts.
The result meant Inter leapfrogged the Moldovan side into second, two points adrift of leaders Real Madrid.
After victory over Sheriff at San Siro a fortnight ago, Inter have now recorded back-to-back Champions League wins for the first time since winning their opening two of the 2018-19 campaign.
"Let's say that this evening we improved our position in the group, now our destiny is in our hands and we must go into the last two games with great concentration," Inzaghi told Mediaset Infinity.
"There was the risk after 10 or 12 chances that we'd get frustrated and frenetic, but instead the lads were always sharp and focused. We made it seem simple, but don't forget Sheriff beat Real Madrid in Madrid and also Shakhtar Donetsk. This gives us more confidence."
Inzaghi's attention now turns to his first Derby della Madonnina against Milan on Sunday, with Inter looking to inflict a first Serie A defeat of the season on their rivals.
"We know what awaits us, it means a lot to our fans and the club," he added. "We must prepare it in the best way with just three days to get ready.
"It's a long flight back to Italy, but we will try to recoup that physical and above all psychological energy."
Brozovic shared Inzaghi's sentiments, saying going back to Italy with maximum points was all that mattered.
"Now we control our own destiny," Brozovic, who scored his first Champions League goal in his 27th appearance in the competition, told Sky Sport Italia.
"The only thing that mattered today was winning. We played really well, attacked and did not allow any counter-attacks.
"The coach said a few things [at half-time], we needed to move the ball quicker and then we'd 100 per cent score a goal."
