Apparently, Simon reckons something more upbeat would've charted higher.
After one week's worth of sales it could be that Louisa misses out on the sought after number one slot, with her single only reaching number nine in the chart on Friday (18 December).
Although there's no way of guaranteeing a chart-topping Christmas number one - Rage Against The Machine beat Joe McElderry back in 2009, and no-one would've predicted that - apparently Simon's record label Syco now think a more upbeat song would've worked better.
A source told The Sun: "It's an embarrassing result for Syco. Even though Louisa had two fewer days of sales, they expected the single to fare much better.
"On reflection, they feel picking a more up-tempo, anthemic song would have been a better idea. But they are fully behind Louisa and insist the poor chart position was down to the song, not the performer."
So who is the lucky artist beating Louisa in the chart race? Well a spokesperson from William Hill told The Daily Star that it's a battle between Justin Bieber's 'Love Yourself' (he is currently number one after knocking Adele off of the top spot) and the NHS Choir's 'A Bridge Over You'.
They said: "It appears that momentum has swung towards Justin Bieber but the Choir are far more festive and they could still easily win this."
