Under-pressure Liverpool boss Rafa Benitez says he has signed a player with "character and a good mentality" after he wrapped up the capture of Maxi Rodriguez on a free transfer. The Reds boss is facing renewed doubts over his future at Anfield following the disatrous 2-1 defeat against Championship side Reading on Wednesday night – a shocking result that sent them packing from this season’s FA Cup. Before the third round replay, Liverpool had confirmed the arrival of experienced Argentinian international Maxi, 29, on a free transfer with the attacking midfielder surprisingly agreeing a three-year deal. And Benitez believes he has secured a bargain as he spoke about his first January transfer window signing. "We were looking for players with character and a good mentality," he said. "I know he was not doing as well as he did in the past at Atletico Madrid, but he is doing really well with Argentina and wants to impress for the World Cup." "I think he will adapt to English football because he is a clever player and takes up good positions on the pitch.” He added: "Rodriguez will be a different kind of player for us and also competition for Dirk Kuyt on the right side, along with Nabil El Zhar and Yossi Benayoun." Liverpool are next in action when they go to Stoke for Saturday's early kick-off.
