What happened: Celtic are now considered favourites to land Las Palmas goalkeeper Dinko Horkas after tabling an offer in the region of £3.5m for the 27-year-old. In a separate strand of Friday's Scottish transfer talk, midfielder Reo Hatate, 30, has confirmed he wants to leave the club this summer in search of a move to one of Europe's leading leagues after missing out on Japan's World Cup squad.

Why it matters: A move for Horkas points to Celtic reinforcing between the posts as they reshape the squad, while Hatate's stated desire to go would remove an established creative midfielder. The parallel departures and arrivals suggest a busy window in which Celtic are active in multiple markets at once.

What to watch: Watch for whether Celtic firm up their interest in Horkas with a formal, agreed fee, and where Hatate's exit search leads as the summer window develops.
