Now 22, he insists that while making the quarter-finals of the Europa League in the club's first season back in continental action after a five-year absence would be an achievement, he would not be satisfied with that.
Santon said: "When we started the season, we had a really good team, but we had some problems because a lot of players were injured.
"But the new players have been really important for us because if we didn't have them, we wouldn't be in this position now, so it was really important for us.
"But I would not be happy to go [only as far as] the quarter-final.
"Like the manager said, I think the same. If we can get to the quarter-final, I think we can win the competition.
"We know in this competition there are a lot of big teams, but I think Newcastle is a big team as well."
