Bastian Schweinsteiger needs no real introduction. He is the modern definition of a superstar footballer. Exactly 500 appearances for Bayern Munich, winning almost every domestic and international honour a player can win, with the European Championships the only real omission and now, at 30 years of age he's become Manchester United's biggest signing of the summer - if not the decade.
Signing a player with Schweinsteiger's talent, profile and experience is second nature and expected for a team like Man Utd, but a 30-year-old with a questionable recent injury record and someone receiving a 30% pay raise to a no doubt already decent package, on top of the purchase of Morgan Schneiderlin does beg the questions: why exactly was he brought to the north of England and why would he want to leave Bayern?
Since the arrival of Pep Guardiola at the Allianz Arena, there has been a palpable shift in what is now required at the top of the Bundesliga. Guardiola has a well documented style of play and players who can fit into this system - Xabi Alonso, Thiago Alcantara and Javi Martinez having all arrived with Guardiola or soon after.

Could this Iberian takeover of Bayern have pushed Schweinsteiger out of the club he has been with since a 14-year-old?
The Red Devils have had a problem berth in central midfield since Roy Keane left for Celtic. The ageing pair of Scholes and Giggs tried to fill the void, along with a whole raft of substandard potentials.

Will the Bastian Schweinsteiger move backfire?
Louis van Gaal himself has tried and tested up to ten different players in the centre of the park without anyone really rising to the role and holding down a starting place.
With Ander Herrera showing glimpses of why United chased him for two years towards the end of last season and Morgan Schneiderlin moving to Old Trafford, this summer United have finally tried to put this issue in their team to rest.
Having played only 82 games for Bayern Munich in the last four years, Bastian's injury trouble are well known and widely written about, and it does beg the question as to why Manchester United would sign an injury prone, 30-year-old just after they have signed arguably the best defensive midfielder in the league.
I find it very difficult to imagine that Schweinsteiger has moved to Manchester for one last pay day, to sit on the bench, or solely play league cup games.
A move to America, China or Qatar, will have provided him with a much quieter end to his career - and with Van Gaal only yesterday saying that he needs another superstar to win the league before he himself leaves in 2017, one has to wonder if he will get the playing time to show the Premier League what he can do.
Or will he be in the shadow of the supposed bigger superstar United crave to return them to the top?
