Bolton Wanderers travel to Portsmouth this weekend as they seek to return to winning ways in League One.
Wanderers make the journey to Fratton Park aiming to build on coming from behind last weekend to claim a point in the 2-2 draw against Gillingham.
It ended a losing streak of three matches and Wanderers will be seeking their first win in the division since the victory over Shrewsbury Town at the start of October.

Bolton have experienced injury blows to the likes of Gethin Jones and Amadou Bakayoko, as well as the departure of previous skipper Antoni Sarcevic to Stockport County.
With what he has at his disposal now, Evatt has not ruled out the prospect of switching formation from their preferred 4-3-3 which has been successfully employed since the second half of last campaign.
Evatt told the Manchester Evening News: "Our philosophy and identity will never change – we’re always going to try to be a possession-based football team.
"But the tactics around that could obviously change. We’ll never lose our belief and identity because once you’ve done that, you’re on a hiding to nothing.
"You’ve got to stick to your beliefs but there are changes and tweaks you can make. For instance, we were 3-5-2 for a lot of last season and then we changed to 4-3-3.
"We’ve been 4-2-3-1, we’ve had pivots with two eights. We’ve got that to able to adapt and tinker with.
"We’ve probably got the players to be able to play three at the back again now. When you’ve got people missing, you’ve got to look at what system best suits the personnel available.
"We’ll do that on a match-by-match basis. We’ll never stick to one formation, it’s always about adapting and overcoming."
Should Wanderers switch to a three at the back, Will Aimson would most likely line up in central defence with Ricardo Almeida Santos and George Johnston, who is fit to play after coming off at half-time against the Gills.
If this was the case, then Lloyd Isgrove would likely be right wing-back, with Declan John on the left.
In a back four were to be played, then Isgrove and John could play on the right and the left respectively, with Santos and Johnston the likely central defensive partnership.
The central midfield trio of MJ Williams, Josh Sheehan and Kieran Lee would be likely to start.
With the absence of the injured Bakayoko, Elias Kachunga is likely to line up on the right, with Eoin Doyle through the middle and Dapo Afolayan on the left flank.
Predicted Bolton Wanderers team to play vs Portsmouth: Dixon; Isgrove, Santos, Johnston, John; Williams, Lee, Sheehan; Kachunga, Doyle, Afolayan.
