I'd be worried about his mentality/ego if he is resigned to the bench, and the impact he would have on the development of Solanke/Wilson/Woodburn if he steals their playing minutes, HOWEVER he is a potential match winner who I think is a good addition to our attack for the fee.
Yeah, fair enough. You'd be happier seeing Shaqiri coming off the bench than Solanke or Woodburn, but it's hard to see him getting games ahead of Mane or Salah, because they're both miles better than him.
So he'll have to be happy being a reserve, unless Klopp's got some mad ideas about the attacking midfield options centrally, with Coutinho gone, the Fekir deal collapsing and Chamberlain injured.
