The Colombian made his return from injury on Friday night in the 2-0 win over Beira-Mar and could play a key role against the Spanish side. His creativity alongside the striker is a key source of danger for Porto, who will no doubt get chances to find the net should they get the 21-year-old on the ball. He is not only a source of invention, though, as he has chipped in with seven goals in 13 Primeira Liga appearances so far this season.

The 20-year-old has been making waves across Europe with some fantastic displays in the hole behind the striker. He possesses awesome technique and seems to be able to keep the ball glued to his feet, even when under heavy pressure. His vision and ability to pick the killer pass have proved to be the undoing of a number of sides this season, so Porto will need to watch him closely if they are to avoid tasting defeat at home to Spanish opposition once more.
