Microsoft Test Manager's interface like for Selenium

Whe are making a proposal to a client for a test automation framework and we are between MTM and Selenium. For what they need (CI process, and manual launch of testing bateryes) is better Selenium.

But in our last meeting the client's head of develop told us that they like the MTM's interface Test Center, because they could unify the automated testing and the manual testing in one interface. So I'm looking for some framework that would provide a similar interface, work with Selenium automated tests and, If possible, interact with their TFS.

Any suggestions?

Thank you a lot.
