Alba is one of the 2-3 best LB's in the world at the moment, so no shame in that. I'm not talking him up at all, but Hunter/Lowe/etc certainly are - and they watch a ton more La Liga than I do so I'll take their word for it. 8.5 million quid isn't a big fee either - if we decided to sell Gibbs I've no doubt at all that we'd get more than that, and this new guy is at least as good/better than Gibbs. As stated, Santos simply couln't play for Arsenal again. Against Munchen, I'd be shocked if we don't plug Coquelin/Koscielny at LB... but the run in for CL next season is much more important to Arsenal right now than CL is - simply not good enough to beat Bayern over two legs - let alone Barca/RM/Manc, so being cup tied doesn't mean too much imo.
