Liverpool defender Martin Skrtel admits he can be a nightmare facing teammate Luis Suarez in training.
Skrtel says it is not just opposition defenders who are struggling to thwart the January buy.
"You try and get close to Luis in training and he will turn you. You give him a bit of space and he will also turn you," Skrtel told LFC Weekly.
"Luis is one of those players that is unpredictable; although he is very consistent, you also don't know what he will do.
"For that reason, I think he will become a very important player for Liverpool and someone who the fans will really like.
"He can change a game in one moment and create something from anywhere on the pitch. As a defender, you have to watch him for every second of the match."
