Mikel Merino, the third of Borussia Dortmund's six summer signings, made his Black and Yellow debut in Thursday's 3-2 win over FC St. Pauli. The Spaniard played on the left of the back three.

Marc Bartra and Emre Mor, together with other EURO participants Roman Bürki, Nuri Sahin and US international Christian Pulisic, are expected back on 18 July. Raphael Guerreiro will return to club duty on 1 August – as will Julian Weigl and Lukasz Piszczek.

Speaking in Kirchberg, Hans-Joachim Watzke said: "We have conducted nine transfers, selling three players and buying six new ones. That is already more than we usually do, but there will still definitely be further deals to be done in both directions." (br)
