To be very honest, I believe him when he says that we haven't yet put in the offer.
It is mainly because there hasn't been any news broken by any other source. It has only been Times and Goal dot com bluffing on the Times news.
Now, if we do put in an offer for Fellaini, his people would definitely contact Chelsea and United and may be one or two foreign clubs to check if there is interest from elsewhere. They would try to attract more attention towards the player, if only to get a better wage deal from us. And there has been no leaks or news breaking in from their side.
If the transfer clause has been activated and they are in talks with us, we'd hear more noise.
