Shearer told The Express: "I have to say I do find it hard to say why he chose QPR over Newcastle. Anybody can choose what they want and I am going to be biased. I will tell you what a great football club it is.
"But it is a tough one for the fans to see Remy so close and then choose QPR. Harry will tell you a different story but I would have a good guess that financial things had a part to play.
"Why he did it, you'll have to ask him. But it's left Newcastle with a huge gap to fill. The manager has tried to do that. Hopefully, they will have a plan B and a plan C. They are desperately in need of players."
Remy's move to QPR has reportedly made the striker the club's record signing.
