At the bottom of the league relegation candidates including Burnley and Sheffield United need something to change if they are to avoid a return to the Championship. NationalWorld looks at which one player each of the 20 Premier League clubs should look at signing on Deadline Day.
1. Arsenal - Amadou Onana
Mikel Arteta suggested no big deals would be done this month, which suggests the rife rumours of a move to Onana may not have legs. The midfielder is a real talent who is fast becoming a standout in the Premier League. Photo: Getty Images

4. Brentford - Eddie Nketiah
Brentford need forward options and news that a deal for Antonio Nusa may fall through is not good. Crystal Palace have been linked with Nketiah, who Arsenal are reluctant to let leave this month, but he'd do a sterling job in West London. Photo: Getty Images
