Wales play Switzerland in their Euro 2020 opener on Saturday.
Here, the PA news agency puts the focus on the Switzerland team ahead of the Group A clash at the Olympic Stadium in Baku.
Petkovic prefers to keep his opponents guessing over formations and tactics. The fact Switzerland’s players are dotted all around Europe’s top leagues now ensures Petkovic’s squad are able to adapt to subtle tactical tweaks. Petkovic has tended to favour close modifications of 3-4-2-1 and 5-4-1 formations, meaning his system could be similar or identical to that of Wales. Switzerland will be stubborn in their defensive shape and keen to break forward quickly in transition, while getting Liverpool’s Xherdan Shaqiri on the ball to do maximum damage.
