Colchester-born Kinsella, who signed for the club as an eight-year-old, capped of a solid performance against the Black Cats by unleashing a long-distance effort which left goalkeeper Jon McLaughlin helpless as his side exited the FA Cup at the Second Round stage.
Liam, who has formed solid partnerships with both George Dobson and Isaiah Osbourne so far this season, has made eighteen appearances over the course of the campaign and is keen to add more goals to his game in order to continue his spell in the first-team.
22-year-old Kins also believes that the Saddlers more than held their own against the much-fancied Black Cats with goalkeeper Liam Roberts not having the busiest of nights between the sticks as the Saddlers stuck to their guns and ultimately booked their spot against Bolton Wanderers in the Third Round.
Speaking via the club's official website - www.Saddlers.co.uk - Liam said; "I just took a touch on the edge of the box and I thought I might as well give it a go. Thankfully it has gone in. I didn’t really know what to do, I didn’t know how to celebrate so I just ran to celebrate with the fans.
"In centre midfield, goals are something that I have got to try and add into my game. I have got to try and score more often and thankfully I have scored against Sunderland.
"When we watch the games back, we will always try and get central midfielders on the edge of the box picking to ball up to have a shot on goal and luckily it came to me on the edge of the box and I was able to get a strike away.
"I don’t think Robbo had much to do. I think we had the better chances throughout the game. We had a few in the first half and thankfully we went on to get a clean sheet and the win.
"The confidence for me keeps building week in, week out and I am getting a run of games now and I am enjoying my football. Hopefully I get can better and better with the more games that I play."
