Kieran Tierney was delighted with a winning Arsenal debut against Carabao Cup opponents Nottingham Forest.

Tierney signed for Arsenal from Celtic during the summer transfer window, but had been suffering from a groin problem since May.

The Gunners were not put off by those issues given that the 22-year-old is seen as a long-term solution at left-back, and Tierney was named in Unai Emery's starting lineup for the first time in Tuesday night's Carabao Cup tie against Nottingham Forest at the Emirates.

Tierney was afforded a warm welcome by the Arsenal fans in north London, and his debut was a strong one as the Gunners eased to a 5-0 victory over Forest.

Later, Tierney wrote: "Thank you so much for all your support... very grateful. Great feeling making my debut!"
