The risk as I see it, in buying a player in his late 20's from abroad, is that they often take a season or so to acclimatise to the pace and style of Premier League football, and there's less of career to play with after the adjustment. This is what in my view would make Pedersen or Downing a better option. They're both quality players who have no need to adjust.
From what I've seen this season the adjustment-factor concerning bulgarians coming to the PL does not seem to be a problem...
