Manchester United have made Bayern Munich an offer in the region of £50m to bring Thomas Muller to Old Trafford, according to reports.
Notable figures at the Bundesliga club, including Karl-Heinz Rummenigge, have issued a number of hands-off warnings to possible suitors in recent weeks.
According to Kicker, however, the Red Devils are hoping that a £50m offer for the World Cup winner will be enough to tempt Bayern into letting him go.
Muller has scored 121 goals in 304 outings for the Bavarians.
