Williams, who joined United for a club record fee of £70,000 from League of Wales club Barry Town, has scored only twice this season, and has been out for two weeks with a hip injury, sustained in a 1-1 draw with Barnsley. Williams says of his injury "It is getting better and I am hopeful for Saturday, you have to be really.
"I have done some jogging and had no adverse effects but will carry on with the treatment today and hopefully join in with the lads today and Friday."
Williams was sold to Hartlepool in March 2002, shortly before the end of his contract, for £30,000 and has scored 37 goals in just over 100 games for the Pool. He said: "It is always nice to score against your old club and I am hoping I get the chance to.
"But the most important thing is to bounce back after Saturday's defeat at Oldham and no matter who is on the scoresheet, it is important we get a win."
Williams has faced his former team mates twice before, and has yet to score against United.
On the match against Torquay, Williams said: "You can't take them for granted. They are a decent side who will hit you on the break if they get the chance.
"They have had a few injuries this season and lost Graham, who was a good player for them.
They had a good result against Stockport (won 2-0) and went 2-0 up against Brentford before ending up with a draw."
Williams still keeps in touch with old team-mate Kevin Hill, who has also been battling with an injury these past few weeks.
The Pools striker added: "I will give Kev a phone before the weekend and see if he is coming up.
"Last time we were speaking about how they always do badly up here and us down there. It must be something to do with the travelling.
"I reckon if we get at them early doors then we may be able to capitalise on their long trip and get at them."
Ironically, Williams first came to Hartlepool's attention on his Torquay United debut, when he scored a fantastic hat-trick, however he never really lived up to his early promise at Plainmoor and ended up with only 24 goals in 118 games. It would be interesting to see how he would fit in to Leroy Rosenior's team though.
