I think at least we'll bring in a CB of some description. There will be plenty of rumors about attacking-mids. Mata isn't going anywhere now he's making an impression at United. What's Shaqiri's status, though? If we have the disposable funds, he is a definite possibility but is he cup-tied? The sad thing is that we have young, dynamic players capable of making an impression in attack that aren't getting enough minutes to show what they're made of. Too much time on the bench can kill a players confidence. When they do get a chance they're in no physical or mental state to play at their best. Bringing in Falcao or Shaqiri just puts those players (Pereyra, Morata, Coman) further at the back of the queue.
It begs the question - can we develop youth at big clubs, or is the prevailing methodology of the past (loan schemes) best? It's a question I still can't confidently answer. Training (and occasionally playing) in teams of a higher level comes with it's own benefits. You're an understudy to some of the best in the world. But the value of regular playing time, albeit in mid-table clubs and relegation fighting teams needs no explanation.
All you can do is look at empirical examples and decide.
One thing I do know is that it's time to load off Llorente and either find a class, experienced replacement or invest the time in Morata. Lord knows we invested the money.
