It is not just the fans of Barca who are pleased as punch right now in the city of Barcelona.
The 25,000 pericos - parakeets - who watch Espanyol regularly have seen their team rise to fourth on the back of a better home record than Barca. Espanyol have won all seven home games this season and sit four points clear of Valencia in fifth. Not bad for a side who have never played Champions League football.
Their latest win came against Sporting Gijon on Sunday when, as in four of their previous home games, it was 1-0 to Espanyol.
The Blanquiazules - blue and whites - spent much of their existence happily ensconced in Sarria, an upper-class neighbourhood of Barcelona close to Camp Nou. It is where Italy beat Brazil 3-2 in their classic 1982 World Cup match and was a typically steep and intimate Spanish inner city stadium, like Valencia's towering Mestalla.
Debts forced Espanyol to sell their old home in 1997 for £45 million and they moved to the unloved 55,000-capacity Olympic Stadium on the hill of Montjuic, a cold athletics venue which was too big for them and not suited for football. Meanwhile, the team trained in six different locations, and whilst the money wiped out their debts, it left nothing towards building a new home. The move was also politically motivated by the authorities, who wanted to save the Olympic Stadium from becoming a white elephant.
Espanyol's fans never loved Montjuic despite their spell there coinciding with half of their entire trophy haul: two Copa del Reys in 2000 and 2006 to go with victories in the competition in 1929 and 1940. It could have been even more, had they beaten Sevilla in the 2007 UEFA Cup final at Hampden Park.
Espanyol fans don't like Barca. They're forever patronised by the media and struggling for oxygen beneath the huge elephant who happens to live in their front room. Espanyol cannot and do not try to compete with the world-famous juggernaut, yet they are proud of their own history and are sixth in the respected all-time Spanish league table behind Real Madrid, Barcelona, Athletic Bilbao, Valencia and Atletico Madrid.
The literal translation of Espanyol is 'Spanish' and the very word seems confrontational to many Catalan nationalists now achieving increased autonomy from the Madrid government. The club was founded months after Barca in 1900 by Spanish students and for Spaniards only. This countered the strong foreign and middle-class influence at Barca, who were formed by a Swiss and included several English students as players. The dynamics of the rivalry were thus established, with Espanyol perceived as the 'anti Barca' and 'anti foreigner' club. Espanyol had Spain's royal crown on its club crest, Barca the Catalan colours. Yet by 1911 Espanyol had three English players in their ranks.
And far from being anti-Catalan today, Espanyol have attempted to capture the zeitgeist and Catalanise their club. In 1995, they changed their name from the Spanish, Real Club Deportivo Español, to the Catalan, Real Club Deportiu Espanyol de Barcelona.
Espanyol's official history was published first in Catalan, not Spanish, and their website's principal language is also Catalan. Whisper it quietly, but they've got just as many Catalan players as Barca.
Espanyol's current success is down to good management and a strong youth system. They finally moved to a new 40,000 home in Cornella on the outskirts of the city in 2009. They will be paying off the move for many years, meaning that money is tight and debts hover around the €140 million mark. Several first-teamers are currently receiving €3,000 a month - with the promise of more when TV money arrives in May.
They are more than earning their corn. As well as their current home form, where they have yet to concede a goal, they beat Atletico Madrid away in spectacular fashion two weeks ago.
Their commitment to attacking football under 38-year-old Argentinian coach Mauricio Pochettino has attracted bigger clubs to some of their most promising names.
Espanyol boast a youth system every bit as impressive as Barca's, though on a smaller scale. Their side contains several locally-born young players who have progressed through the ranks. Central defenders Jordi Amat,18, and Victor Ruiz, 21, are both Catalan. Other locals include left-back Didac, 21 and Javi Marquez, 24, both of whom came through the youth system.
They have flourished after big names like Raul Tamudo and Moises Hurtado departed, while injury has consigned Ivan De La Pena, 34, to a peripheral role. One loss Espanyol are still struggling to get over is captain Dani Jarque, who passed away at the start of last season while on a pre-season tour. Andres Iniesta revealed a message to his former Spain team-mate Jarque after scoring the winning goal in the World Cup final, while fans spend the 21st minute of every game applauding his memory. Jarque wore the number 21.
Coach Pochettino understands the club. A former Espanyol central defender with 275 league games for them in his two spells, England fans might remember him as the Argentina defender who brought down Michael Owen to earn England a penalty and the game's only goal in the 2002 World Cup finals.
The coach mixes youth with shrewdly-purchased imports like top scorer Pablo Osvaldo - whom the noisy fans bowed to in reverential style on Sunday - while Cameroonian international goalkeeper Carlos Kameni is enjoying his seventh season as the first-team shot-stopper. Luis Garcia - not the former Liverpool player 'who drinks Sangria' - remains their talisman.
The fixture list has been kind to Espanyol so far and their home record will be sternly tested in their next home game at Cornella just before Christmas. The visitors are Barca, who have won all seven away games. Espanyol won't be fazed - they've got a habit of upsetting their neighbours and their fans don't mind shouting about it.
