So we have
Coutinho
Firmino
Markovic
Lallana
Ibe
Sterling
Harry Wilson
Ojo
Milner
Who can all play in the same position as Shaqiri?
Why would we spend money on a reject from Germany?
Because he's better than all of the above?
It's all about improving the squad quality. Just because we have good players in one positions it doesn't mean you don't try and improve. Would you turn down the chance to sign Messi just because we already have lambert, borini, ballotelli, ings and origi???
