Herrera missed United’s last game, away to Wolverhampton Wanderers, while Matic was an unused subtitute, and the pair were both absent from the open session at the Aon Training Complex on Tuesday morning.
Solskjaer suggested that Matic could still be involved on Wednesday evening, but was less optimistic about Herrera’s chances of facing the Spanish champions.
“We still hope maybe that Nemanja can be ready, but Ander is probably out,”
said the boss.
“Antonio [Valencia] and Eric [Bailly] are definitely out.”
The Norwegian also provided an update on Marcus Rashford, who was absent at Wolves after injuring his ankle but has since returned to training.
