New X Factor champion Matt Terry will have to fend off competition from former stars of the show if he is to top the chart this week.
Matt's debut single, called When Christmas Comes Around and penned by Ed Sheeran, is up against efforts from One Direction's Louis Tomlinson and former 1D singer Zayn Malik.
But the 23-year-old waiter, from Bromley, is expected to do well despite the track being released late on Sunday evening; singles are generally released on a Friday.
Also doing well at the mid-week stage is Louis's debut solo single Just Hold On, which had a later-than-usual release date following the death of his mother.
The singer launched his track on Saturday evening following his performance on the ITV reality programme, days after his mother passed away at the age of 43.
At the mid-week stage, Just Hold On has entered the chart at number 21 and is expected to climb up the ranks.
Zayn - who formed one-fifth of boy band One Direction for five years until he quit in 2015 - unveiled a new collaboration with Taylor Swift entitled I Don't Wanna Live Forever, and the track has rocketed straight to number five.
These new entries will have to topple Clean Bandit's Rockabye off the top spot, where it has sat for five weeks.
The rest of the top five is made up of Rag'n'Bone Man's Human at number two, The Weeknd's Starboy at number three and Rae Sremmurd track Black Beatles at number four.
In the album chart, the Rolling Stones could retain their number one slot for the second week in a row with their new studio record Blue & Lonesome.
However, collaborative album Together by Michael Ball and Alfie Boe is still selling well despite being on sale for over a month and could reach number one for the first time since its release.
The duo's record is currently at number two ahead of Little Mix's Glory Days in third place, Elvis Presley's The Wonder Of You in fourth and Olly Murs's 24HRS at number five.
