Carlo Ancelotti has revealed that Chelsea are not considering making too many rash signings over the summer transfer period, after their £70 million spending spree in January.
"I don't think there will be a lot of changes during the summer because we bought very important players in January, David Luiz and [Fernando] Torres," the Chelsea manager said.
"I don't think we need to have too many more changes."
Injuries to Ramires, Alex and Branislav Ivanovic have threatened to cause an upset for Chelsea in tonight’s match up with Birmingham, and Ancelotti says that good replacements for the trio have been difficult to find.
"At the start of the season, we couldn't have envisaged having very important players out at the same time,” Ancelotti said.
"We struggled to manage this - without Lampard, Drogba, Essien, Terry, Alex, it was very difficult.
"At a certain point in the season, we needed to put (Paulo) Ferreira in at centre-back because we'd lost all our other centre-backs.”
Ancelotti believes the injuries for Chelsea could not have been foreseen at the beginning of the season, and has represented a huge challenge as Chelsea keep their faint title hopes alive.
"You cannot think at the beginning of the season that you would have all these players out.
“In the bad moments, it was difficult for us to move on without these players and I think it cost us quite a few points."
