Update 5/23/14:
Hello FIFA Ultimate Team fans,
Trading on console and the Mobile Companion App remain available while we continue to work on Transfer Market improvements for FIFA 14. The FUT Web App will continue to be available, but with trading disabled until further notice.
We consider this a priority and have a team working on Transfers to make sure they are optimally functioning across all platforms. We appreciate your patience and apologize for the inconvenience.
The FIFA Team
