Thanks to the team from SouthAmericanFootball.co.uk ( Anthony Wright , Nicholas Rosano , Brian Maxwell , James Walker-Roberts and FOX Soccer's own Rupert Fryer ) we know which of the tournament's 32 remaining clubs can be expected to be around after the group stage of the 2012 Copa Libertadores. The competition starts in earnest on Tuesday. Here are their Group 3 and 4 snapshots:

Snapshots Groups 1-2 Groups 3-4 Groups 5-6 Groups 7-8

GROUP 3 Full group 3 snapshot (SouthAmericanFootball.co.uk) Without a team from Brazil or Argentina, Group 3 is unlikely to garner much international attention, which gives one of last year's quarterfinalists a chance to continue flying under the radar.

Universidad Catolica Country: Chile

Best Finish(es): Runners-up in 1993

Key Player: Felipe Gutierrez

Expectations: Win the group and do damage in the knockout round

FOX Soccer prediction: Group winner

Via SouthAmericanFootball.co.uk: Catolica have all of a sudden found themselves in the shadow of reigning Copa Sudamericana champion Universidad de Chile, both domestically and internationally. Make no mistake though, los Cruzados are a top side. They boast both promising youngsters and experienced veterans, despite the loss of longtime captain Milovan Mirosevic to the Columbus Crew.

Junior Country: Colombia

Best Finish(es): Semifinalists in 1984

Key Player: Giovanni Hernandez

Expectations: Make the next round

FOX Soccer prediction: Second place

Via SouthAmericanFootball.co.uk: Junior have collected two of the last four Colombian championships and put in a very good showing in last year's group stage. They have retained much of the core that carried them to success in 2011, though they will miss the prolific goalscoring of Carlos Bacca, recently sold to Club Brugge in Belgium. Junior can also depend on a strong midfield and defense. Veteran playmaker Giovanni Hernandez will once again be back to pull the strings in midfield.

Union Espanola Country: Chile

Best Finish(es): Runners-up in 1975

Key Player: Sebastian Jaime

Expectations: Compete for second place

FOX Soccer prediction: Third place

Via SouthAmericanFootball.co.uk: A balanced, seasoned team that finished third in last year's combined table in Chile, Union Espanola don't boast too many star names. Backed by an experienced defensive line, they will not be an easy side to break down. Up front, Sebastian Jaime will be the focal point of the attack alongside 22-year-old Jean Paul Pineda.

Bolivar Country: Bolivia

Best Finish(es): Semifinalists in 1986

Key Player: William Ferreira

Expectations: Play spoiler once or twice at home

FOX Soccer prediction: Fourth place

Via SouthAmericanFootball.co.uk: Bolivia's most decorated club, Bolivar qualified for the tournament after winning Bolivia's truncated 2011 Torneo Adecuacion. As is usually the case with teams from La Paz, this young side will have the altitude to aid them, but they can also count on the goals of Uruguayan striker William Ferreira and support from talented young midfielder Rudy Cardozo. They should do well again in Bolivia but may find themselves overmatched on the continental stage.

Snapshots Groups 1-2 Groups 3-4 Groups 5-6 Groups 7-8

GROUP 4 Full group 4 snapshot (SouthAmericanFootball.co.uk) Like Group 1, Group 4 is top-heavy, containing two clubs that could develop into tournament favorites.

Boca Juniors Country: Argentina

Best Finish(es): Copa winners in 1977, 1978, 2000, 2001, 2003, 2007

Key Player: Juan Roman Riquelme

Expectations: To compete for a record-tying seventh title

FOX Soccer prediction: Group winner, if barely

Via SouthAmericanFootball.co.uk: Boca Juniors return to the competition that defined the finest epoch in the club's history when Carlos Bianchi led Los Xeneizes to three Libertadores Cups before Alfio Basile added a fourth four years later. Current coach Julio Falcioni has explicitly stated his desire to add his name to the list of Boca's Libertadores-winning coaches. Boca have a base as solid as anyone else in the competition. Bolstered by the high profile arrivals of Pablo Ledesma and Santiago Silva, Boca will rightly be among the favorites with the bookmakers.

Fluminense Country: Brazil

Best Finish(es): Runners-up in 2008

Key Player: Fred

Expectations: Make a deep run into the tournament

FOX Soccer prediction: Second place

Via SouthAmericanFootball.co.uk: Flu go into this year's Libertadores as a major force. Rafael Sobis has been in fine form since arriving in Rio and, alongside Rafael Moura, could offer considerable support to the prolific Fred. If little Manuel Lanzini and new signing Thiago Neves can supply enough bullets, Flu have the arsenal to fire themselves all the way to the final.

Arsenal de Sarandi Country: Argentina

Best Finish(es): Group stage in 2008

Key Player: Carlos Carbonero

Expectations: Not many, in this group

FOX Soccer prediction: Third place

Via SouthAmericanFootball.co.uk: Founded just over 50 years ago, the club made their Libertadores debut in 2008 and will be hoping to better their performance this time around, having failed to qualify from a group that contained both of that year's finalists. They lost Mauro Óbolo to Velez in the mid-season break but have signed an extremely promising young Colombian in Carlos Carbonero from Estudiantes who was sensational in the first leg of Arsenal's qualifier against Sport Huancayo. He, and his teammates, will have to show cooler heads if they hope to emerge from Group 4.

Zamora Country: Venezuela

Best Finish(es): N/A

Key Player: Dario Figueroa

Expectations: None

FOX Soccer prediction: Fourth place

Via SouthAmericanFootball.co.uk: Zamora make their Copa Libertadores debut after sealing their ticket with the 2011 Venezuelan Torneo Clausura title. Captain Moses Galezo revealed last month that he and his teammates were continuing an adventure after appearing in last year's Sudamericana, and veteran Dario Figueroa is looking forward to the opportunity to get one over on Boca (his former club) at La Bombonera.
