Pep Seeking to Compound Bernabeu Blues
Although the immediate success of his time as Bayern Munich helmsman may make it easier to forget, Pep Guardiola wasn't long ago the bastion of Barcelona, and the Bernabeu will be no strange setting for the Spaniard.
Who will win Wednesday's first leg?
During his time as Barca boss, Guardiola led La Blaugrana into 15 El Clasico fixtures, winning nine and drawing four. It's a remarkable record of extremely positive connotations for Der FCB as we lead into Wednesday's meeting, one would have to agree.
And he'll seek to use that advantage to his favour against Carlo Ancelotti's men. Just as is the case with Jose Mourinho, ex-Real Madrid coach, now taking Chelsea to face Atletico Madrid, Guardiola has a new weapon at his disposal, but is up against an old foe.
Ancelotti will be all too aware of that aspect of the fixture, but let's not forget that it hasn't been so long since Real and Bayern last clashed in direct competition.
Los Merengues were knocked out of the 2011-12 Champions League campaign at this very stage two years ago, Bayern proceeding to the final after winning 3-1 on spot kicks.
One could argue back and forth about who has improved more since that meeting, but the truth is that the margins will be so fine in this regard that either side may still come out on top, should the right amount of momentum run in their favour.
These two teams have met 11 times over the past 37 years of European Cup and Champions League competition, with Bayern winning on four of the six times that those matches have come under semi-final conditions.
History would dictate that Real have more reason to be bitter toward their impending opponents, but will that work for or against the Spanish hosts on Wednesday?
Gareth Bale vs. David Alaba
Two of the stellar performers for their respective sides so far this season, Gareth Bale and David Alaba will be readying themselves for a head-to-head that promises to take them all over the Bernabeu turf on Wednesday.
As the Manchester Evening News' Rob Dawson pointed out when Bayern clashed with Manchester United in the tournament's quarter-finals, Alaba tends to wander under Guardiola's tactics:
Lahm and Alaba giving United a problem when Bayern go forward. Becoming two extra central midfielders. Always an option around the area.— Rob Dawson (@RobDawsonMEN) April 9, 2014
However, the left-back may be instructed to take up a more strict regime with the threat of Bale bearing down upon him, the Welshman fresh after scoring the superb winner in last weekend's Copa del Rey final triumph over Barcelona.
Bleacher Report's Stefan Bienkowski also points out how effective Alaba can be with the ball at this feet:
Batten a goal down? Pep brings on Alaba. How outstanding he is going forward.— Stefan Bienkowski (@SBienkowski) April 5, 2014
On Wednesday, these two are likely to have a large impact on how successful their outfits are moving forward, but only one will be majorly concerned with how his defence fares, and that promises to be a pivotal point of influence on who emerges as victor.
