Ivanovic brushed off the rumors, though, and said this about the situation:
"I won the Champions League just one week ago and to think about changing clubs now is complicated. I am very happy in London."
He didn't confirm or deny anything with that statement, and it doesn't seem as though he knows what he wants to make of his future just yet. Real Madrid will definitely be willing to fork over the necessary funds to secure his services, but Ivanovic would be wise to stay with the Blues.
While his team won a championship this year, he didn't play in the Champions League final after he was suspended three games for punching Wigan forward Shaun Maloney in the back. He definitely contributed to the team's success this season, but it would be surprising if he didn't feel as though he had some unfinished business to take care of at Stamford Bridge.
The Chelsea defense is one of the club's strengths, while Mourinho wants to bring in the 28-year-old Serbian center back to fix the back line at Real Madrid. Madrid's defense cannot compare to the likes of Ivanovic, Ashley Cole, John Terry, Michael Essien and David Luiz. This defensive group at Stamford Bridge works well together, and the back line has developed good chemistry with one another.
Another problem with Ivanovic's prospective departure is that he plays the same position of Sergio Ramos. If he signs on with Real Madrid, he would surely get playing time at that position, but at what cost? He would be thrown into a defense when he doesn't know the tendencies of his teammates as well as he does at Chelsea. It would take him awhile to get acclimated, and he would most likely garner some scorn from the Madrid fans while he was getting comfortable.
Not only should he not leave, Chelsea cannot afford to let him flee for greener pastures. The Blues will already be without Didier Drogba next season. Losing Ivanovic would leave them without two of the starting 11 players from their championship campaign. It would be a huge public relations gaffe to let Ivanovic go on his way, and the fans wouldn't be pleased with the departure of two key players the season after winning a title.
Ivanovic says he is happy in London, but sometimes money can make a man change his mind. If Real Madrid offers him the right price, even though it wouldn't be wise for him to do so, it would be hard to blame Ivanovic for leaving for a hefty sum.
