Barcelona stumbled in Vitoria after a first half they would rather forget. It forced Koeman to make drastic changes at half-time. The coach replaced three of his men and took a risk with the departure of Lenglet.
With the Frenchman coming off, Frenkie de Jong took up his position and played for 45 minutes as a defender, something that he already had to do in Turin, on that occasion due to the injury of Araujo.
Barcelona were not any worse off for his change of position, in both Turin and Vitoria. However, they lacked a goal they needed to come away with all three points.
It's worth remembering that De Jong already played as a defender at Ajax, although his performance there had not been too good.
The Dutchman started the move that almost gave Barca the comeback. He found Trincao, who gave it to Griezmann for a 2-1 lead, but the Portuguese player was offside and the goal was disallowed.
Regardless of the bad result, Koeman has made it clear after these two games that De Jong can be that fourth dream centre-back that he could not sign in the last market.
