It was a controversial one.
Ramos made 2 faults that wasn't counted against Lenglet because he continued to play like nothing happened and referees didn't see it. Then Lenglet pulled Ramos's shirt which was an obvious obstruction, however Ramos love dramatising the situation a bit and acted like he was in the pool.
Anyway it is Barcelona fault for not scoring, so crying about the VAR being always against them will not fix their problemS!
