Liverpool goalkeeper Alisson admits he studies rivals to help improve his game.
The former Roma man says he's studying the performances of two top stoppers to improve his game.
"I like [Jan] Oblak; he's one I follow very closely, and [Marc-Andre] Ter Stegen," said Alisson to Goal.com.
“There are others, but at this point, these are the ones that are showing more.
"Very high technical level, very high concentration level too; they are raising the competition level among us goalkeepers.
"It's a healthy competition to see which of us will be the best at the end of the year."
