Suso has insisted that Liverpool teammate Raheem Sterling's performance for England against Norway earlier this week was not a surprise.
The 19-year-old, who has already scored twice in the Premier League this season, has earned plaudits for his performance at Wembley on Wednesday evening.
The midfielder told the club's website: "I remember the first year I came when I was at the academy in the reserve team. He was in the Under-18s team and he played some really good games. Obviously he was really young at just 16 but you could see he had the quality to be a good player.
"Now he is in the first team you can see he has improved a lot and he is still improving and every time you see him play, he is normally the best player on the pitch.
"He was man of the match for England against Norway and it's really nice to see how he has grown playing alongside him. He is a really nice lad as well because he always listens to you every time you talk with him and if he has to learn something he learns it. He is a fantastic boy to be honest."
Sterling has earned eight caps for England since making his debut in November 2012.
