It is the eight day period that will define the reign of Jose Mourinho, coach of Spanish giants Real Madrid.
And it got off to the perfect start as the Portuguese manager led his side to a crucial 3-1 victory at archrivals Barcelona to seal a place in the Spanish Cup final -- one of only two trophies left for the club to win.
Now, after another meeting with Barcelona on Saturday in the league, Mourinho will turn his thoughts to the second leg of their last 16 European Champions League tie against English Premier League leaders Manchester United which arrives next week. The sides drew 1-1 in the first leg.
Real trail Barca by 14 points in the league, meaning retaining their title is surely beyond them, but with Mourinho seemingly destined to leave the club at the end of the season his tenure will only be deemed a success should he complete a cup double before May is out.
