Oxlade-Chamberlain signs new one-year Celtic deal

Oxlade-Chamberlain's partner, Little Mix singer Perrie Edwards, had gone public on social media about her desire for an extended stay with Celtic and Scotland and the player himself expressed his delight about his new deal on the club website.

"It was an incredible time last season and to be part of that success in winning the league and Scottish Cup was so special," he said.

"I'm really excited to be back and I'm looking forward to meeting up with the boys and getting to work ahead of what will hopefully be another successful season."

O'Neill's squad head out to Ireland this weekend before their first pre-season match against Shelbourne on Tuesday.

Alex Oxlade-Chamberlain, capped 35 times and who played for Southampton, Arsenal and Liverpool, will then join up at their training camp in Portugal.

Celtic have yet to make any new signings this summer.
