When and Where: The CONCACAF Champions League semi-final first-leg kicks-off from the Estadio Tecnologico in Monterrey at 10 p.m. ET. A live stream will be available with a subscription on CONCACAFTV.

Preview: Monterrey face familiar foes Pumas UNAM as they look to move one step closer to retaining their CONCACAF Champions League title they won for the first time with victory over Real Salt Lake last year.

And recent form points toward Monterrey progressing to another final in 2012. The Rayados currently sit in fourth spot in the Clausura table, having lost just once in 10 matches, and looking good for a playoff spot.

Things are not going so well for Pumas, however. The 2011 Clausura champions currently lie in 14th spot in the standings and their chances look increasingly remote of making it to the playoffs.

Yet the teams drew 1-1 when they last met in January in Monterrey, a result that would surely suit Pumas once more with the second-leg to come at home next week.

Monterrey will be looking for more goals from veteran Chilean striker Humberto Suazo. The 30-year-old scored twice in each leg of Monterrey's 7-2 aggregate victory over Morelia in the last round.

Other key players for the home side will be striker Jesus De Nigris, who has hit seven goals in 10 matches in the Clausura, as well as former Argentinian international Cesar Delgado. All three hit the back of the net in Monterrey's 4-0 win over Estudiantes Tecos at the weekend.

Pumas reached this stage of the competition courtesy of a 9-2 aggregate win over Metapan. Amazingly, Pumas lost the first-leg 2-1, before going on to win 8-0 in the return.

Prediction:  Monterrey seem to be returning to the form that win them the CONCACAF Champions League last season and will start as strong favorites to get a first-leg lead over Pumas. Monterrey have been scoring goals for fun at home and will just have to ensure they don't concede an away goal.
