Plzen were in the Quarter finals of the Conference the season before, Hearts looked shite but so did they. A shite Hearts actually looked in control for big stretches away in the first leg.
The reality is neither of those teams will pick up many coefficient points in the Europa, but both should be a good team in the Conference and at least make the knockouts (no doubt Hearts will implode). Do feel what the nation needs, and historically we've lacked, is a team like Hearts or Aberdeen to have regular group stage football where the money would be significant and they can grow to compete against these teams outside the top leagues.
Kilmarnock shat the bed against the Belguims when there wasnt much between them. They were there for the taking and would of given them a much easier tie in the Conference playoffs. Bit unfortunate against Copenhagen, who they made look shit in the second leg, with the first leg apparently being a snorefest outside of a couple of lucky goals. Think Hearts drew them and imagine theyd be content with that draw.
