He was called in the Bulgaria national football team while playing for Botev and was considered likely to be selected for the 1994 World Cup, but eventually did not make the final squad.

[3][4] Vidolov was sold to CSKA Sofia in the autumn of 1996, after Botev started to experience financial troubles.

Vidolov signed with CSKA Sofia in the summer of 2000, taking an instrumental part in their 2000/01 run for the championship title.

Vidolov played two seasons for the German club, with whom he qualified for the final of DFB-Pokal, before moving back to Bulgaria.

He played for three seasons with Botev Plovdiv – a disagreement between him and the club owner Dimitar Hristolov drove Vidolov out in the summer of 2007.

In January 2008, the veteran signed with Beroe Stara Zagora, in an attempt to save the team from relegation.
