I don't see any problem with spending big in January if RK feels the need.
A top class striker for the inevitable injury/suspension to Pelle, a GK and we're nearly there.
It's one of those rare seasons where, at the moment, a CL place appears to be up for grabs.
There will never be a better time for a team like Saints to break into the top four. Arsenal and Utd will also be spending big this next window in an attempt to make it as well.
If we do spend big, those new players will also be a magnet for others in the summer.
Seems like a win/win situation to me....
