Juventus general director Giuseppe Marotta has made it clear that the Bianconeri will continue to strengthen their squad in the future, as he has promised that more new signings will arrive in Turin in the summer.Players such as Eljero Elia, Andrea Pirlo, Arturo Vidal and Mirko Vucinic all found their way to the Old Lady in the summer of 2011, with Marco Borriello, Ouasim Bouy and Simone Padoin following suit this winter.The Bianconeri are not done just yet though as Marotta has insisted that they will continue to add fresh blood to their ranks.\"It\'s a bit premature to already talk about it, but the process of renewing the team will continue in the summer,\" Marotta said to Tuttosport.The Juve chief refused to mention any potential transfer targets, but the Turin based daily claims that Real Madrid attacker Gonzalo Higuain is one of the Bianconeri\'s top transfer targets at the end of the season.The Argentine attacker has been used in a squad rotation system at Madrid so far this term, and could be allowed to move on at the end of the 2011-12 campaign.
