£23m is a lot of money, but to be fair money needed to be spent at Liverpool. Ngog remained a 2nd striker for far too long at a club that was meant to be aiming to challenge for top honours. Having said that, he could find himself there again if Torres leaves, although no one sees them as that threat any more.
Will be interesting to see if they can hang on to Torres, and either way what way they'll line up, and then obviously how Suarez adapts and both the short and long term impact he has.
You'd imagine a step in the right direction for Liverpool, but still some way off the top 4 though in spite of this I'd say.
