Celtic will not entertain offers for Callum Osmand this summer, with Martin O'Neill determined to keep the young striker at Parkhead despite West Ham circling. Osmand enjoyed a breakthrough season following his arrival from Fulham, scoring a title-clinching goal that helped secure the Premiership crown. The club's resolve is strengthened by the expected summer departure of Daizen Maeda, making Osmand's retention a genuine priority for O'Neill's squad rebuild. A Transfer Insider podcast source confirmed Celtic "will not be keen on letting Osmand go" after such an eventful campaign, cementing his status as a key piece in the champions' plans for the season ahead.
