Marvin Friedrich is on the move, and this one is done. The 30-year-old German defender is leaving Borussia Mönchengladbach to rejoin Union Berlin, the club where he made his name before. The deal is confirmed and structured as a free transfer, with Friedrich valued at around £3m. There is no haggling left to do here — the player and both clubs have settled it, and the story has reached its conclusion rather than its negotiation. The reporting comes from Florian Plettenberg, a reliable voice on German transfer matters, who carries solid credibility. At present this rests on his word alone rather than a chorus of corroboration, but given the move is already confirmed, the single source is reporting an outcome rather than chasing a rumour. The engine sits at 100%, which is as emphatic as it gets. That figure reflects a deal that is not merely likely but settled: the terms are agreed, the fee is a free, and nothing of substance stands between Friedrich and his return to Union Berlin. When a move is confirmed and the financials are this simple, there is no realistic path to collapse, and the number says exactly that. This is a homecoming. Friedrich first joined Union Berlin from Augsburg for £2m in 2019, then left them for Mönchengladbach in a £5m move in 2022. A free transfer back to Union now sits comfortably below both of those figures, which is unsurprising for a 30-year-old returning to familiar ground. With the deal confirmed, the next thing to watch is the official announcement and the medical formalities being completed.
