Whilst there was a thought that Pep Guardiola's arrival at Bayern Munich might make it more difficult for foreign sides to sign Borussia Dortmund players who were keen to face off against his side, it would be unexpected if the Bundesliga champions were to lose a star player to Bayern themselves.
However Sky Italia have reported that Robert Lewandowski is very near agreeing a move to Bayern, and this wouldn't just be a huge blow to Dortmund in their attempts to challenge Guardiola's Bayern next season, it would also be an indication that English sides might struggle to compete with Bayern for the very top players in the transfer market.
Although there was rumoured to be interest from Chelsea, Arsenal and Tottenham Hotspur too, it is Manchester United who have been the presumed destination for Lewandowski for the past couple of years. Whilst there doesn't seem to be a need for another striker at Old Trafford right now, the rumours had shown no sign of going away, with a move expected to go through in the summer.
So if Lewandowski was to snub the Premier League, and Manchester United in particular, it could be said that something must have changed his mind, and Guardiola's arrival at Bayern Munich might well be the reason.
Another interesting part of the reports is that Lewandowski is not a typical Guardiola player. He is mobile and technically sound when on the ball, but clearly using the Pole to lead the line would be a departure from the system he used with Lionel Messi at Barcelona, although this might just be an indication Guardiola is wisely trying to set up a system that doesn't rely on a uniquely brilliant talent like the Argentine.
It is only rumours at this stage, but if Robert Lewandowski does end up going to Bayern Munich a lot of interesting questions will be thrown up, and the answers might not make pretty reading for the Premier League.
