Mark Hughes has warned Manchester City fans they will not truly see the benefit of his extensive squad reshuffle until next season.
The arrival of Shay Given from Newcastle completed a hectic transfer window for the City manager, although he missed out on Brazilian superstar Kaka, Hughes signed Wayne Bridge, Nigel de Jong and Craig Bellamy.
With Given also added to a squad that contained four new faces from the Sven-Goran Eriksson era, including British record signing Robinho, the Blues have undergone major surgery.
It means Hughes is expecting major improvement during the second half of the season, starting against Middlesbrough today.
But the former Wales chief feels it will be the start of next season before the true measure of the changes he has made are seen.
"People don't understand how much of a change has been undertaken here," he said.
"The alterations we have made on and off the field have been vast.
"Certainly I am confident about the impact they will have and I am looking for a strong second half to the season.
"But in addition, the way we do our work on a daily basis will have a positive impact going into next season."
