Barcelona could make a move for Juventus' unsettled midfielder Tiago Mendes in a swap deal involving Mexican defender Rafael Marquez, Calcio Italia magazine reported. The Catalans are ready to make an approach for Portuguese midfielder Tiago because the versatile Marquez hasn't been at his best in the Primera Liga this season. On the other hand, Tiago hasn't been successful in forcing his way into Claudio Ranieri's squad since joining from French champions Lyon in the close season. According to the Italian magazine, both players have agreed in principle to swap clubs. However, Marquez's wage demands could prove to be the stumbling block.
