Swansea striker Beattie delighted with winning comeback
The 27-year-old, who linked up well with Stephen Dobbie, hopes his performance will now help him stake a claim in Brendan Rodgers' first team.
Beattie said: "It was a good exercise. A lot of the lads got a good 45 minutes under their belt before the international break to freshen up and some of the young lads came in to get some experience, so it was a good night.
"I'm feeling really good. The specialist told me 10-12 weeks at the start and I've managed to get it down to four so it was good to get 45 minutes and a goal as well.
"We hit them on the break and it was a nice cut back from Dobbs - I managed to get a sidefoot on it and put it in the corner.
"We've not played together much since we have been here but I thought we linked up well."
