Barcelona star Xavi has launched a fresh attack on Real Madrid coach Jose Mourinho. Xavi says Mou will forever live in the shadow of former Barca coach Pep Guardiola.

"Mourinho is not going to go down in football history," the Spain star told Canal+. "For me, the best is Guardiola, and in the four years that he has been leading the club, he has revolutionised football.

"For example, Chelsea won the Champions League this year, but the club [Barca] remains the benchmark in world football."
