He's 31, on hefty wages and West Brom want £3(+) million for him - if it's true that Charlie Austin (at 23 and on less wages) can be got for £4 million, I know who I'd prefer us to go for. Build for the future, not for just one season.
Coupled with his ability to simply discard a club he's playing for and being paid by, it could be a risky move. Imagine if he's our main goalscorer, looking set for a mid-table finish come the end of the season if we carry on at the same rate we have in the first half of the season - January turns up and his goal-scoring exploits have attracted interest from other clubs and he wants out, leaving our second half of the season in tatters.
That said, if we sign him, I'll back him and back Brucie - at least he'd guarantee goals.
