He told City's website: "We have lost Jo for quite some time now, and he has not had a great deal of football recently either, which is a concern for us.
"We send them away with our best wishes, you do hope that while they are away that they will get good game-time under his belt. But he has not had a great deal of football in the time he has been away, so hopefully he can hit the ground running.
"He has been in competitive games, but going in for 10-15 minutes a time is not the ideal preparation for Premier League games, so it might take a little bit of time to get up to speed. But needs must, and I think he will be involved with us very, very quickly.
"We hope that he will settle very quickly, he has got the ability to and he will give us a presence up front which we lacked last weekend. He's exceptional in the air and he will give us a bit extra."
