Know where you're coming from, but don't endorse the Harry comparisons.
Harry was never one striker away from a great side. He was 5-10 average players over quota every season and got himself caught in a sell to buy cycle. He then ended up loaning out over 25's just to get back to a squad of 25. If he had managed his squad better, he wouldn't have wasted his available funds on players salaries that he would never use. He did what Harry typically does, and spun a yarn that his chairman wouldn't buy him a striker. Don't kid a kidder as they say.
Most of Poch's tenure, he's been willing to offload unwanted players and kept his squad small. He has created space constantly for incoming players of a certain quality but not always bought well. He is way more deserving of a big signing than Harry ever was in my opinion, but needs to keep offloading the fringe and applying pressure to his boss to bring in quality.
