Barcelona director Raul Sanllehi admits Chelsea's winter market spending shocked Europe.
Speaking to reporters at the annual assembly of the European Club Association in Geneva, Sanllehi said Chelsea's January outlay had stunned everyone.
Sanllehi says Chelsea's outlay shocked them with UEFA demanding tight financial controls.
"Of course we have a budget, but a budget is like a blanket," Sanllehi added. "If you pull it up to your chin, you need your feet to stay warm."
