Torres and Mascherano were teammates at Liverpool from 2007 to 2010.
Neither player picked up a trophy during their time under Rafa Benítez.
The Argentinean was signed by Liverpool from West Ham during the 2006/07 winter transfer window and Torres joined six months later from Atlètico de Madrid. During the three years they were together under Rafa Benítez, Liverpool failed to win a single trophy and soon after Mascherano joined Barça in 2010, Torres was also on the move, joining Chelsea in the winter of 2010-11.
At Liverpool, Torres scored 69 goals in 143 Premier League games, whilst Mascherano managed one in 94 games.
Should Di Matteo and Guardiola play them, the two are likely to have plenty of opportunity to renew their acquaintance, with Mascherano now a key member of the Barça back line, after playing primarily as a midfielder during his time at Anfield. (via FCBarcelona.com)
