Liverpool coach Mauricio Pellegrino says former Espanyol winger Albert Riera is a great signing for the club.

"I remember playing against Riera when he was at Mallorca. He is a player with great quality," Pellegrino told the official LFC Magazine.

"Wingers who can beat their man and get to the byline are quite rare compared to years ago when many teams played with wide men like this. Riera is the type of footballer who is hard to find now.

"Now, it is difficult to find players with these qualities anywhere in the world. Many wingers nowadays always go inside the defender. When they are one-on-one, they tend to go inside rather than on the outside. Riera can take his man on and get quality crosses into the box. He just needs to develop here and gain the confidence to take it into our team now."

The Argentine coach also believes Riera can bring much more than just wide play to the team.

"Reira is good in the air too," adds Pellegrino. "He is a good jumper and that is also important for us. Set-pieces are an important area of play in the Premier League. Many teams focus on this and have players who are good at set-pieces.

"Because Riera can head the ball well, he can bring a new dimension to our attack but will also be useful when we are defending set-pieces.

"A little like myself, he has to adapt to our ideas and systems as quickly as possible.

"I wish him all the best."
