The Austrian had been injured in the fast 3: 4 in the first leg and was not available at the weekend in the 4-0 win against Espanyol Barcelona, who secured the 35th Spanish championship title.
As Spanish media, above all the specialty sheets Marca and AS, report, head coach Carlo Ancelotti did not call the 29-year-old into the training group, who was prepared for the Mancity game on Wednesday on Monday.
He was “practically excluded” for the game.
It is not known what injury Alaba suffered.
However, the international took part in the master celebrations.
The former Bayern professional could replace Nacho, who had already taken Alaba’s place in the first leg at the beginning of the second half.
The defense lawyer’s failure still affects the royal, Alaba posted the most play minutes this season after goalkeeper Thibaut Courtois and defender Militao.
