I'd say no deal for Schurrle. His wages are pretty high, and frankly, he's not as monstrous in this version, as he was in the last. He is transfer listed every time by Chelsea.
As for Wanyama, he's among the best BWM ingame. But that deal still seems a bit high for me, but he's worth every penny nevertheless. If you haven't already confirmed the deal, sell Matuidi, and try to reduce the monthly payments for Wanyama, by increasing the one-time payment. It should help with your overall finances too, and clubs accept lesser bids with one-time amount.
As an alternative to Wanyama, you can try Papadopoulous. He goes absolutely nuts as a BWM.
