What happened: Alex Oxlade-Chamberlain has signed a new one-year deal with Celtic. The 32-year-old England-capped midfielder joined the Glasgow club in February after six months out of the game following his release by Besiktas, and scored a last-minute winner on his debut against Livingston.

Why it matters: Oxlade-Chamberlain was part of Celtic's late-season revival under Martin O'Neill, who took the job permanently after the club retained the league title with a final-day win over Hearts and lifted the Scottish Cup. With Celtic yet to make a new signing this summer, keeping the veteran midfielder gives O'Neill continuity heading into pre-season.

What to watch: Celtic head to Ireland this weekend before opening pre-season against Shelbourne on Tuesday, after which Oxlade-Chamberlain joins the squad's training camp in Portugal.
