Manchester City have completed the signing of Espanyol winger Albert Riera on loan for the rest of the season. The Spaniard could make his debut in Saturday's FA Cup tie at home to Scunthorpe subject to international clearance. Manager Stuart Pearce admitted he had been watching the player for some time. "We tracked him when he was at Bordeaux and last summer he moved to Espanyol," Pearce told the club's website. "We saw the opportunity when things hadn't worked out there to bring him here and he's on loan until the summer. If things work out well for him here we might well keep him on beyond that." The winger has been handed the number 19 shirt and Pearce believes he will add a new dimension to the side. "Albert's a naturally left-sided player and gives a natural balance on that side," said the manager. "It's another new face into the side and he's of a good age at 23 years old. We're hoping he'll do well for us. "When you get players on loan you don't really want to give them a month or two to settle in. Only his ability will dictate that and how quickly and well he settles in. "Albert's got a grasp of the English language but we'll try pick up on that as much as possible and filtering him into the side."
