Xherdan Shaqiri moved to Bayern Munich with much fanfare. At the time he'd already impressed European football with FC Basel and was considered one of the best young players in the game. Bayern got themselves something of a coup and his signing was a big deal throughout Europe. Shaqiri had been been linked with Europe's top clubs and eventually joined one of the very biggest.
The Switzerland international cost around £10m largely due to his contract situation and the move was announced several months before the transfer actually happened. Last season Shaqiri started 13 Bundesliga games, with the same again in substitute appearances. Under Pep Guardiola he's going to struggle to get the same game time.
Right now some midfielders are injured at Bayern Munich, including Thiago and Javi Martinez, when the Spaniards return it's hard to see how Shaqiri gets a look in, especially with Pep's desire to turn any good player into a midfielder. Shaqiri is mainly a winger who would prefer a more central role, but out wide it's perhaps even harder to get into this Bayern team with Arjen Robben and Franck Ribery holding the slots and displaced central midfielders looking to pick up the pieces.
The 21 year old could feel he'd be better off long term elsewhere and whoever signed Shaqiri would be getting a wonderfully talented player. Switzerland's Infoticker says that Arsenal are interested in making a €15m move for the player in January.
He's got a contract running until June 2016, Bayern Munich would be keen to keep him as long as they can give him game time once the injured players are back.
