London - Roman Abramovich is ready to hand current Barcelona coach Pep Guardiola a four-year deal worth £40 million, after tax, to become Chelsea boss. According to The Sun website, the club's billionaire Russian owner has refused to give up on his quest to lure Barcelona's all-conquering manager. And that includes making Guardiola the highest-paid boss in the world with a money-no-object offer worth £10m a year in cash, according to one Blues insider. Guardiola's Nou Camp deal is up at the end of the season and Abramovich will not call off the chase while the manager leaves his future up in the air. Guardiola currently earns around £8m a year nett at Barcelona. Sacked Andre Villas-Boas was paid about £4.5m a year and Chelsea coughed up £13m compensation to his previous club Porto to release him last summer. Abramovich has forked out in excess of £2 billion since taking over at Stamford Bridge only nine years ago. If he persuades Guardiola, 41, to become his eighth boss, Abramovich will have spent almost £150m on managers alone in wages, compensations and payoffs.
