London - Chelsea defender Branislav Ivanovic has warned Manchester City that the Premier League leaders are back to full power heading into their seismic showdown at Stamford Bridge on Saturday.
Jose Mourinho's side are five points clear of second placed City and Ivanovic claims they are confident of extending that lead over the champions after a much-needed morale boost in the League Cup in midweek.
Stung by their humiliating FA Cup fourth round defeat against third tier Bradford last weekend, the Blues responded impressively by booking a League Cup final berth thanks to a 1-0 semi-final second leg win over Liverpool.
The victory was secured by Ivanovic's extra-time goal and the Serbia international celebrated by insisting the result was a sign Chelsea are ready to hit peak form in the crucial clash against City.
"We showed the real power of our team and in the end deserved to be in the final," Ivanovic said.
"We know we can improve and we'll improve in the next couple of games."
