Barcelona won the game against Elche win a 4-0 result and Real Madrid won the game against Real Valladolid with a 6-0 result which can show us both teams are very much ready for the El Clasico and they are showing each other how dangerous strikers they have to score 4 and 6 goals. Also, for Real Madrid, this game can be an excellent chance to take revenge after losing 3 El Clasico matches in this season.
Real Madrid striker is far more fertile than the Barcelona striker in terms of scoring goals this season, but the El Clasico match will be far from estimates and might surprise the end result. Benzema's first leg did not get a chance to score goals and vice versa for Lewandowski, so that in the second leg it would be quite interesting if the two could prove each other.
Both teams are in perfect condition at this time, I want to see Real Madrid make a comeback in the match or score one goal faster to equalize aggregates, so that the match is more interesting and takes place hard.
Regardless of who won the match with a lot of goals or few goals, in fact these two teams are both ready to continue the final battle to qualify for the Copa Del Rey final.
It's true that both of them are in good form, but I think Xavi has a good plan to avoid defeat in the semi-final second leg. At least Xavi expected draw for qualified to final, but I think win can also be expected. Now Frank Kessie will be heavily marked instead of another player.
Likewise with Ancelotti must have a special strategy to face Barcelona at Camp Nou. I am sure Real Madrid will play attack and will try to make a fast goal to equalize the aggregate, Benzema who is in a fit condition can also help Real Madrid comeback like defeating Liverpool.
We will see the extent of the ability of the two coaches in making decisions and what strategies will be used to get satisfying results in the match, the advantage of the cage for Barcelona is not very influential in my opinion in this match.
