The summer transfer window of 2025 saw seven players leave Celtic, marking a busy period for the club without any major signings.
Kieran Tierney was one of the notable arrivals, while Greg Taylor departed as his contract expired, drawing attention in the opposite direction.

The departure of Taylor was anticipated, along with Daniel Cummings’ move to join the English Premier League team West Ham United.
The trend of academy players leaving Celtic for English clubs continued, with the likes of Rocco Vata, Ben Doak, and Mikey Johnston making similar moves in recent years.

Hugh Keevins expressed his frustration on Clyde 1 Superscoreboard over Cummings’ departure and Celtic’s subsequent recruitment of Callum Osmand from Fulham.
The financial gap between English clubs and Celtic makes it challenging for the Scottish side to compete for wages, leading to the departure of promising talents like Cummings.

While Cummings transitioned from Celtic’s youth setup to West Ham’s U21 team, his future development remains uncertain. The exodus of academy players to English clubs reflects the changing landscape of football economics between the two countries.
