I am not a huge fan of loans, and it may not be able to happen now Gotze is on his way out. Next season I wouldn't mind trying to get Leonardo Bittencourt on loan from Dortmund. A very good prospect and hasn't been given too many games purely because Dortmund have so many talented attacking players.
I think the question would be whether he could handle the rigours of the Premier League as he is perhaps slightly lightweight, as well as that he will be 20 in December so is very young. Would he be worth a look at on loan?
Not a rumour by the way, just a suggestion.
Also saw about Sam Byram posted above, I would love to see him at our club but would probably have to ship him out on loan first season, purely because he isn't quite as good as Whittaker or Martin YET. I think he would cost us £5 mill minimum either way, and he is being linked with some more established Prem teams who can perhaps afford to invest that kind of money in the future. It's a lot of money for us to invest on someone who won't really improve our team straightaway which we have to do.
