O’Sullivan’s signing follows that of fellow striker Emily Thomson from SWPL rivals Celtic, as City look to strengthen their strangehold on the Scottish Women’s Premier League and look to progress in the Champion League past the group stages once more.
City head coach Eddie Wolecki Black, commenting on the signing of O’Sullivan, said: “I first saw Denise play for Republic of Ireland against Wales back in 2011. It was her first team debut and she marked it by scoring both goals in a 2-0 win. Her overall performance that day caught not only my attention but captured the imagination of the crowd. Little did I think we would be working together less than two years later.
“Once I knew Denise was a potential signing for us I immediately asked the club to make it happen. It is to their immense credit that Laura (Montgomery) and Cas (Carol Anne Stewart) have managed to get her signature. Denise will report to training next week. She will add creativity, versatility and goals to our squad and there is no doubt her new team mates will benefit from her arrival. I am very much looking forward to working with Denise and wish her all the best with the club.”
She has played 18 times for the Republic of Ireland scoring four times, including in the 2-1 defeat to Scotland in the UEFA 2013 qualifiers back in April 2012.
