The referee standing along the goal line did not call this a goal. I really can't blame the referee given how fast the above play moved in real time. There may have been poetic justice in the "no goal" call because Ukraine was offside earlier in the attack, but that doesn't change the fact that replay is needed to decide calls like the one shown above. Goal-line technology is here and is easy to implement. The above image could have been created seconds after the play and a decision could have been made within a minute of stopping play. There aren't that many goals in a typical football game, and there certainly aren't that many controversial goals. In a given tournament, there are, what, one or two (at most) controversial goals that could benefit from replay?
Join the 21st century and get the call right!
