Portsmouth set to sign Millwall midfielderÂ

The News understands the midfielder is closing in on a move to Fratton Park. 

Thompson is a product of the Lions' youth academy and made 38 League One appearances when they won promotion to the Championship via the play-offs in 2017.

However, the 22-year-old has since fallen out of favour at the Den.

He featured just eight times last season, with only three of those outings coming in the Championship, while he hasn't featured in either of Millwall's league games this term. 

Thompson looks set to become Kenny Jackett's eighth signing of the summer and second loan arrival after David Wheeler.
