He obviously had a decent offer from Palace on the table, and it was a move he could make without even having to uproot his family. No brainer.
Seriously, whats he supposed to do ? Say "oh no, I can't sign for them because thats the Brighton fans main rivals" ?? Get real, how childish would...
I honestly couldn't give a flying f**k at a rolling donut about his Palace links. If he comes back and bags half a dozen goals for us between now and the end of the season, then that'll do me just DANDY.
