ASSISTANT boss Matt Gill admitted there will again be changes when Saints host Watford in the FA Cup fourth round replay tonight. 

Manager Russell Martin switched nine of his league team for the 1-1 draw at Vicarage Road last month. 

An Anfield clash with Liverpool at the end of the month awaits the winners of the St Mary's meeting (7:45pm). 

Starters Mason Holgate and Charly Alcaraz have departed the club since the initial match. Here is how we think Saints will line up... 

Goalkeeper 

Joe Lumley has been the cup stopper and that is unlikely to change after Martin praised his performance at Vicarage Road.

Defenders 

Jack Stephens and Jayden Meghoma can give the two full-backs a rest with both likely to start as the respective flanking defenders. 

Jan Bednarek and Taylor Harwood-Bellis do not have any reliable backup with Stephens on the right after Mason Holgate's departure.

Midfielders 

Shea Charles could operate at right-back or centre-back but started as the natural holding midfielder last time out in the cup.

Will Smallbone might keep his place - as per the last round - while Joe Rothwell will have another chance to start his second match for Saints.

Attackers 

Adam Armstrong was one of the four game-changing substitutes last time out but with David Brooks cup tied he could be start.

Sekou Mara is in line for another start while Sam Edozie might just be ready for some minutes - he may only come off the bench, though.
