In this sort of situation I usually look for intent. If it's genuinely careless - ie a player taking too little care accidentally 'breaks up a promising attack' - but advantage develops, then I see no need for a card, but I'll be warning the player to take more care, especially in that area of the field.
However, if it's a blatant attempt to break up a promising attack - ie an ultimately unsuccessful attempt at a tactical or 'professional' foul - then I'm still giving the caution regardless of outcome.
