winger

But Pep appears to be very cautious at the moment, and has not been using his out-and-out wingers, Doku or Savinho, very much because he wants to try to control the middle of the pitch.

The winger was injured by a high challenge on the back of his ankle in the 32nd minute by Leif Davis, who was sent off.

"Essentially what Barcelona do is put a winger on the left side for decoration," Ibaceta said.

Like Alexander-Arnold, Doue likes receiving the ball deeper in his own half before progressing the ball further up the pitch with long passes forward to his winger or striker.

The wingers disappear, the three-player triangle in midfield becomes a box-shape four, and the other side has to scramble to keep up.
