Rosler have overseen the arrivals of Ross Turnbull, Sol Bamba, Tom Adeyemi, Lee Erwin and Chris Wood this summer, but a left winger has eluded the new Leeds boss so far.
Now though, London 24 report that Leeds have agreed a deal to sign Northern Ireland international Dallas on a three-year deal as he nears a reunion with Rosler.
The duo worked together at Brentford, and after an impressive campaign last term, Dallas is set to leave Griffin Park to work with Rosler once again.
After HITC reported earlier today that Leeds were pushing to sign Dallas, the most recent development states that a £1.2m fee has been agreed with the Bees to take the wide man to Elland Road.

The stats above show that Dallas was an effective force in the final third for Brentford, contributing assists and goals as well as key passes and crosses into the box.
That's exactly what Leeds need ahead of the new Championship season, and weakening a Championship rival is also an added bonus for Rosler's men.
Rosler has been backed with funds to sign Dallas, and much will be expected from him as he gets ready to become Leeds' first choice winger.
