Liverpool played with 4-3-3 line up. Inter played with 3-5-2 line up. When Liverpool were in set attack, Inter were 5-3-2 now. Wing backs were in defense line. Normally, they were matching with Liverpool’s full backs 1 by 1 but now, if Liverpool’s full backs were not closer to Inter’s defense line, wing backs couldn’t match with Liverpool’s full backs directly. If they would want to match, this time they would be too far away from defense line. And Liverpool tried to benefit from this situation especially from right back.
Liverpool’s left back was taking position in wing. So Inter’s right wing back could close to him comfortably if left back could be dangerous for Inter. Because when left back went forward from wing, he was also closing to Inter’s right wing back too and they could match directly.
But Liverpool’s right back took position in half-space and helped midfielders about making game. So this time, Inter’s left wing back couldn’t match with right back directly. So now Liverpool had one extra player in midfield.
And if Liverpool’s right winger was taking position in half-space, Inter’s both left stopper and left wing back were careful about right winger. Normally, Inter’s left stopper was matching with right winger 1 by 1 but because left wing back wasn’t marking any player now, he took position closer to right winger too.
So in a situation like this, when right back took the ball, right winger closed to wing a little bit and right centre midfielder closed to forward. Inter’s left centre midfielder shifted to right back because now right back was a central threat for Inter. Inter’s left wing back closed to forward a little bit. Now he was closer to right back more. Left stopper followed Liverpool’s right winger. So this time, Liverpool’s right centre midfielder was free in right half-space closer to forward.
