Millwall Signs Wolfsberger Winger Thierno Ballo on Season-Long Loan, Sells Adam Mayor to Cambridge United

Millwall has been active in the transfer market to strengthen their squad for the 2025/26 season, focusing on attacking reinforcements. They have signed winger Thierno Ballo on a season-long loan from Wolfsberger AC, with an option to make the deal permanent next summer; Ballo is noted for his pace, flair, and versatility across the front line. Additionally, striker Nisbet is set to leave Millwall to rejoin Aberdeen on a three-year deal after a successful loan spell, while young midfielder Adam Mayor has joined Cambridge United on loan to gain more first-team experience under former Millwall boss Neil Harris. Manager Alex Neil has been seeking to improve the team's attacking threat, which has shown inconsistency despite some strong performances and a promising EFL Cup run. These moves reflect Millwall's intent to bolster their squad depth and creativity as they aim to climb the Championship standings. The club's transfer strategy involves both bringing in proven talent like Ballo and facilitating player development through strategic loans.
