Kompany has been one of the Blues outstanding performers this season.
It was a slight surprise the Belgian was not included in the short-list for PFA player of the year and he undoubtedly will be one of the men Manchester United must find a way past if they are to emerge victorious in tomorrow's FA Cup semi-final derby encounter at Wembley.
Aiming high: Kolarov believes Kompany (left) can be as good as Vidic (right)
After observing Kompany's consistency at close quarters during his debut season with the Eastlands outfit, Kolarov can pay the 25-year-old no greater honour than to compare him with Serbia teammate Vidic, a man he has been close friends with for so long, and someone who will be barring City's path to glory.
'You have to remember that Vinnie is younger than Vidic,' he said.
'He has done really well for us this season.
'I'm lucky to be able to play alongside him and if he continues the way he is going he can be as good as Vidic.'
It is no small praise for Kompany given he believes Vidic, who did make the PFA's seven-man shortlist, is currently the best defender in the Premier League.

'I know Nemanja very well,' said Kolarov.
'We play together in the national team but I have known him since he played for Red Star Belgrade.
'He's a great player, and I'm not just saying that because he's my friend.
'I know he is the United captain but I really do think he's the best defender in England. And if you are the best in the English league you are the best in Europe in my opinion.'
Not that there will be any respect on show when referee Mike Dean blows his whistle to start such an eagerly-anticipated clash.
'We'll say hello but that will be it,' said Kolarov.
