Birmingham City boss Alex McLeish says Ben Foster will relish his return to Manchester United today.
Foster left United in the summer for St Andrew's in a £6 million deal.
Ahead of today's Old Trafford clash, Blues boss McLeish said: "It's fantastic for Ben, a great occasion going back there.
"He's stuck to his business after the mistake at West Ham in the Carling Cup.
"He was very, very solid last week against Aston Villa."
