Uncertainty still surrounds the long-term future of Newcastle United interim head coach John Carver - with the club yet to announce whether or not he will be retained beyond the end of the current campaign. Steve McClaren remains the bookmakers' favourite to move into the St James' Park dugout next season, while Carver could yet be given the job on a permanent basis if he keeps the Magpies in the Premier League. But a new name has entered the fray in recent days - that of Rayo Vallecano boss Paco Jemez. The 45-year-old former Spain and Deportivo La Coruna centre-back - who is known commonly as "Paco" - has been in charge at the Madrid minnows for almost three seasons now, and he has impressed during his time in the role. But, apart from the fact he is a former international centre-back who has coached Rayo Vallecano for three years, there is much else that Magpies supporters should know about Jemez. For this is a man who has been praised by Pep Guardiola, who has publicly labelled Zinedine Zidane as an "embarrassment", and who once declared: "When a coach asked me to kick the ball long I f***ing hated it, because what I liked was played football." Well, here are 12 things that every Newcastle United fan should know about Rayo Vallecano head coach Paco Jemez, who has been touted as a possible replacement for John Carver as Magpies boss.
