However, Swansea are thought to be holding out for £5million for the 27-year-old, due to a 50% sell-on clause held by his former club ADO Den Haag.
Megson said: "I'm not going to lie, we have made an offer for Ferrie. We are where we are with that one and if Swansea do want to do business it will be on the price we have last done at.
"Otherwise we will move on because we have got one or two midfielders here that I'm pleased with and every player has their price so we won't go above what we have offered so far."
