In Germany, Bayern Munich is considering a loan move for 19-year-old midfielder Felipe Chavez to increase his playing time. Potential suitors include several second-division German clubs and the Portuguese side Estrela Amadora.

In the Netherlands, Feyenoord is investigating an incident where fireworks thrown by visiting supporters caused injuries, including burns and ocular damage, to SC Cambuur fans.
