German club Stuttgart had a mixed 2009-10 season.

Another Uruguayan Ajax star Nicolas Lodeiro was also sent off, when he picked up two bookings after coming on a substitute during Uruguay’s opening day draw with France.
As Lodeiro will also miss the semifinal meeting with Holland through injury, Ajax’s Dutch stars will not come up against their club mates.
