He played against Leeds two years ago, for Newcastle at St James' Park, and was given a rough reception from the visiting fans and is now braced for another torrid time during Sunday's friendly.
Leeds tried to sign him last month, and even though Newcastle offered to pay half his £60,000 per week wages, he snubbed the offer from his old club.
So he can expect the worst when he heads to Elland Road.
Alan Smith: "I don’t know what the reception will be - we played them at St James’ Park two seasons ago and I got a bad one then, so I am expecting the same at Elland Road.
"I have been back to watch games but never as a player. It is not something I have really wanted to do to be honest.
"I have a great affiliation with the club, they brought me through. I was an academy player and a senior player when I left.
"I am not going to go into details as to the destination I went to. I don’t want to touch on it. People will express how they feel and I know that.
"I hope that whatever happens people have seen when I'm playing I am giving it everything."
