Well he did say this directly after...
"We have to speak with the club about what is the situation, because hopefully Vincent can help us, but Vincent in the last two years he was like this [with injuries].
"We have Nico [Otamendi], John [Stones] and [Aleksandar] Kolarov, and Kola is a full-back, and of course we have Tosin [Adarabioyo], and Tosin is still young. When we arrive now in the Premier League, in the FA Cup, in the Champions League, if something happens with the injuries we don't have enough.
"We are evaluating if there's a chance to take one.
I know Holger, he's a fantastic player, a fantastic guy, but he's a Bayern Munich player, and we should first of all speak with them and with him.
"Now on the table there are no names because we had a lot of games, but now we have 10 days off, 10 days until Everton, so we have time to discuss with [director of football] Txiki [Begiristain], with the club, what is the best for the rest of the season."
