German defender Lennard Sowah is training with Millwall in an attempt to earn a loan deal.
The 19-year-old left-back is presently with the Lions with a view to joining the club from Hamburg on a deal until the end of the season.
Sowah has previously had a spell in England with Portsmouth, where he made five appearances in 2010, while he has also been capped by Germany at youth level.
Millwall confirmed the defender's trial in a statement on their official website, which read: "Young German left-back Lennard Sowah is training with Millwall with a view to signing on loan until the end of the season."
Kenny Jackett's side on Tuesday evening host Watford in the Championship at The Den.
