@James I think you need to ask yourself whether he's behind Morata, because if so he's destined to sit on the bench and won't earn many dividends. But if you think he could nab a starting position, you'd get an absolute bargain with potential for big returns.
The important thing on FI is to take a long term view rather than getting swept away in the immediate fervour; is Giroud going to be holding his value in six months, one year, three years? My instinct is not, and so I'd leave this one. There's definite potential to try a risky short-term flip but I'd recommend you get to understand the Index a little more before trying that.
