Ibrox side Glasgow Rangers won 4-0 on Tuesday night.
The Gers midfielder was on international duty with Canada for the Gold Cup earlier this month.
Rangers kicked off their season with a rousing 4-0 win away to St Joseph's in the first round of Europa League qualification on Tuesday night.
And although Arfield was not in the squad, Gerrard told The Mail that the former Burnley star is back training with his side.
He said: "We have got plenty to go and I think we are only 70 or 80 per cent in terms of being match fit and tuned in.
"Scotty Arfield has just joined us, so he will boost us again. We are in a good place, we are happy where we are up until now. But I will keep pushing them individually and as a group to keep fine tuning it to make sure we are ready."
Surprisingly, it was a goalless first half with the Gibraltar-based club, but Ryan Jack fired Rangers ahead on 50 minutes.
From there it was a walk in the park for Gerrard's side as goals from Sheyi Ojo - on his debut - Borna Barisic and Alfredo Morelos made it a rout.
It'll be good for the light Blues if they have Arfield back for the next round, assuming that the Scots see out this tie at Ibrox next week.
The next round is bound to be a lot tougher and having someone like Arfield - who scored 12 goals from midfield last season - would be a welcome boost.
