In-form Inter Milan head to Barcelona on Wednesday night aiming to maintain their impressive run of form, knowing that victory will put them on the brink of a place in the last 16 of the Champions League.
The Nerazzurri have won seven matches in a row in all competitions, including each of their opening Group B fixtures to join Barca on six points from six.
Inter, who have progressed out of the group stage in each of their last eight participations in UEFA's premier competition, are sweating on the fitness of a couple of key men ahead of their trip to Catalonia.
Here, Sports Mole looks at how the Italian side could line up at Camp Nou.
Luciano Spalletti will monitor the fitness of Perisic after the Croatian attacker limped off with a thigh injury during Inter's 1-0 win over AC Milan at the weekend.
Compatriot Brozovic came through the full 90 minutes despite also carrying a thigh problem, and both men are expected to get the nod for this seventh-ever competitive meeting between Inter and Barca.
Should Perisic be fit to feature, Spalletti will likely stick with a 4-2-3-1 formation, which will almost certainly be spearheaded by Real Madrid-linked striker Mauro Icardi.
A change will be required in attacking midfield, however, as Nainggolan - on the scoresheet against PSV Eindhoven three weeks ago - injured his ankle against AC Milan, so Lautaro Martinez may be handed his first Champions League start.
