Relax folks, 3-1 isn't that a bad a result.
It only hurts as much because we were leading by a goal up at half-time, before we ran out of steam.
All of us had agree that Sevilla deserved a win after a dominant second half performance and as much as we would have preferred a 2-1 defeat, 3-1 it is and thus, it stays.

You should remember we were playing with inexperienced Mino, Gomez, Romeu, dos Santos in our starting lineup. Add to that, the tiring legs of Alves and Ibrahimovic.
Definitely not our strongest lineup. In fact, far from it.
And to make matters worse, Bojan and Abidal had a bad day at work.

Overcoming a 2-0 deficit in a return leg at home is very much possible.
Unlike Inter Milan, Sevilla do not have the defensive prowess to park the bus and hold our full-strength squad to a goal or less.
Also, keep in mind that Sevilla would be playing Sporting Braga in the CL play-off midweek.
So, expect a less resilient Sevilla side at Camp Nou next weekend.

To discuss the performance of our youth players and the need for further signings,
here was an outing wherein our senior players Bojan, Abidal were terrible while Milito, Alves were plain average.
To assess our cantera products under these circumstances would be unfair to them.
So, dismissing them as thrash makes no sense.
That said, that is no excuse for avoiding talks of their inexperience.
Romeu, Gomez were only decent until the goals started pouring in.
Granted that Milito and Abidal weren't exactly positive influences but yet, we could have done with more maturity from your second-choice holding midfielder and fourth-choice centre-back.
Afterall, we are a club that's reckoned as the team to beat in all competitions.
dos Santos wasn't very impressive either and Thiago – he hardly got the chance to prove his point.
However, I believe that with either of Xavi/Iniesta/Busquets to support them, they could be counted on.
The same cannot be said about the defensive side of our squad. CB and DM are very sensitive positions and more often than not, one mistake from either could cost you a goal and the match!
Ideally, a competitive club plays with 5 CBs in its squad. With only Puyol, Pique and Milito to account for, we are assuredly lacking in this department. Fontas/Muniesa could be our 5th choice but certainly, not 4th. While some might suppose that even the 4th choice centre-back had be hardly used, I would remind you of CL quarter-finals return leg where we neither had Puyol nor Pique to anchor our backline. I am not sure if Fontas/Muniesa/Gomez would be up to that challenge and a CB is a position I had prefer not risking to find out.
Oriol Romeu was good in the first half but given his anonymous second half, I doubt if I could confidently field him against Chelsea or Man Utd or even, Inter Milan.
So far, he has only played regularly in the third division and U-19/U-20 tournaments wherein his opponents were weak, either physically or technically. Thereby, I believe he would be better off developing in the Segunda division than being rushed to the senior team wherein the first game he is asked to start is against Chelsea! Drogba or any physical forward would humour his growing limbs.
Give him atleast another season with Athletic before we burden him with great expectations.

Thereby,
in my opinion, we need a CB <– I would prefer to retain the services of Caceres than splash the cash.
and a midfielder – need not be a Mascherano whose popularity cannot be accommodated on the bench, but definitely someone who can fill Busquet's boots in his absence.
or a utility player like Capoue who can play both CB and DM
or a versatile midfielder like Banega who can play both DM and CM.

And yes, the MediaPro bankruptcy has left us with limited transfer funds but Rosell has assured that cash upto 50 million would be made available for further signings. Following that public announcement, we have only spent 9.5 million on Adriano … thereby, I am certain that one more signing would not be as much of a financial burden as many of you believe.
