The goalkeeper, who last appeared for Ronald Koeman’s men in March 2015, enjoyed a relatively quiet night on his return as Saints prevailed thanks to goals from Shane Long and Dušan Tadić.
And the England international was thrilled to pick up an important victory in his first game back.
“It was brilliant – I wasn’t overworked by any stretch of the imagination. It was a fantastic team performance,” Forster told youtube.com/southamptonfc
“It’s a performance all the lads can be pleased with. The manager came up with a good game-plan and we stuck to it.
“Credit where it’s due, we did well and hopefully we can build on it.
“It was nice to get another 90 minutes under my belt. It means a bit more confidence will come back. I’ll just work as hard as I can in training and see where it takes us.
“It will give us a lot of confidence – everyone did amazingly well. It will be fantastic to take that forward and build on it.”
The stopper says he felt like he’d never been away as he slotted back in with ease – aided by an impressive defensive performance as Koeman opted to play a 3-5-2 against the Hornets.
“It felt like any other game and I felt like I hadn’t been away,” he added. “I’ve played so many times with [Ryan] Bertrand and José [Fonte], and I played with Virgil [van Dijk] at Celtic.
“We have a great relationship and understanding and they performed really well.
“They really limited them to few opportunities. It was a fantastic team performance and so easy to slot back in.”
