Says he is unable to speak about any proposed deal with Brighton owner Tony Bloom over recruitment, but stressed Hearts are always "looking to improve and progress". Naismith stressed data is not just about "general output from players". He says it is key at every level of a club and will be even more so in the future. He understands the buck stops with him when it comes to results after seven consecutive defeats. "We need to be better, and that's ultimately my mistake and my problem." Says there have been key areas identified for improvement - "we need to be creating more chances; we need to take more chances" - but also believes Hearts have lacked luck in certain games.
