Bristol City wing-back Ryan Fredericks has signed for Championship rivals Fulham, only 25 days after joining the Robins from Tottenham Hotspur.
The 22-year-old joined City for an undisclosed fee on a three-year contract on 6 August.
He started four of City's opening five matches, but has now signed a three-year deal with the Cottagers.
"When I heard of the interest from Fulham I jumped at the chance," said Fredericks.
"I'm delighted that we got it done so quickly. It's a massive club that belongs back in the Premier League.
Fulham's a great area with big fans - it's a good club."
Fulham Football Statement
The Club is delighted to announce the signing of Ryan Fredericks on a three-year deal from Bristol City for an undisclosed fee.
A right-back by trade, Fredericks came through the Tottenham Hotspur academy, making his debut for the club in a goalless draw with Hearts in the UEFA Europa League Play-Offs in 2011, before featuring twice in the Group Stage.
The following season he made five appearances on loan at Brentford before being recalled to White Hart Lane.
Fredericks tasted European football again for Spurs in a 4-1 win against Anzhi Makhachkala in December 2013, before joining Millwall on loan the following month. His spell in South-East London saw him sample regular first team football as he played 14 times in the Championship, and scored the winning goal on his Lions debut against Ipswich Town.
He agreed a season-long loan deal to Middlesbrough last term and featured 19 times - including twice against Fulham - as the Teeside club reached the Play-Off Final.
The 22-year-old then joined Bristol City on a permanent deal earlier this month, and featured five times for the Robins prior to joining the Whites.
Fredericks said: "When I heard of the interest from Fulham I jumped at the chance and I'm delighted that we got it done so quickly.
"It's a massive club that belongs back in the Premier League. Fulham's a great area with big fans - it's a good club."
