The matches at White Hart Lane form the centrepiece of our pre-season preparations and such tough fixtures should ensure the boys are more than ready and match sharp for the big kick-off against Everton on August 17.
"They'll be great games for us," said Simon. "Playing Celtic, they've got great supporters and hopefully they'll bring a lot down here - it should be a great game.
"They'll be nearly at the top of their fitness and it'll be a great test for us to see where we are."
