Striker Aaron Connolly is in line to make his second Championship debut against Hull City for a second different club in the space of four months.

The former City man, who departed the MKM Stadium at the end of last season after his contract wasn't renewed by the Tigers, has left Sunderland to join Saturday's opponents Millwall.

Connolly penned a permanent deal at The Den after having his one-year contract at the Stadium of Light cancelled by mutual consent, and he goes straight into Alex Neil's squad for the 12:30pm clash with City at The Den on Saturday.

City's popular former frontman played just 10 times under Regis Le Bris on Wearside with his debut coming off the bench in the 1-0 win at City in October, while his solitary goal came against the Lions in a 1-1 draw in Bermondsey in November.

"We're pleased to bring Aaron into the club," Lions director of football Kevin Gallen confessed. "When Alex and I met him, we really liked his enthusiasm for what we want to do here. Aaron's been a bit unlucky not to play a bit more at Sunderland this season, but that has given us an opportunity to get him in. Still only 24, Aaron has a lot of experience for his age. He is at his best when running at defenders and we hope he gets plenty of opportunities to do that with us."

Speaking about his departure from Sunderland after a short spell in the North East, the 24-year-old said he was in a good place as he prepared for the latest chapter of an eventful career.

“When I spoke to Kristjaan (Kristaan Speakman, Sunderland sporting director), I just thanked him for the opportunity this club gave me when many others wouldn’t," Connolly said. "It is something I will never forget, and the love I felt from the fans after my first interview until my final game is something that I will always be grateful for.

"Physically and mentally, I leave Sunderland in a good place, and I owe a lot of that to the people at the club, including my team-mates and the staff. I’m now ready to play games regularly, and I appreciate the club’s understanding in allowing me to pursue this opportunity. I wish everyone at Sunderland the best of luck for what I’m sure will be a memorable end to a great season.”
