Speaking to the media, Parkinson said: "I don't think we are a million miles off in terms of the numbers where we want to be. Obviously we are always looking if we can add a player or two of quality.
"We know the players we would like; we will keep trying to get the player or players in and if we do, great. If not, we have got a strong squad and we will go with what we've got.
Parkinson added: "When we target a player, we decide on where we feel that valuation is and more often than not we stick to it. That's what we will continue to do."
