"I had no problem with David leaving for Manchester United. As managers, you have to be ruthless and make decisions that are not going to make people happy," Stubbs told the Daily Mail.
"I think Everton fans wished him all the best. Now he's come back for two of our players, he is public enemy number one. That's football. He'll have to accept that.
"He's said in the past Everton don't sell cheap and then comes in with a £28million bid for I think the best left-back in the country and one of the best midfielders.

"But it might take a bit of pressure off Wayne Rooney when he comes back to Goodison because he won't be public enemy number one anymore. So he'll be happy!"
