The manager went into the game without a recognised left-back, without injured central defenders Ledley King and Michael Dawson and Scott Parker sidelined with Achilles trouble.
Gareth Bale stepped back into his old left-back role and Jake Livermore returned to central midfield.
The pre-match problems were compounded by injuries to Younes Kaboul and Kyle Walker during the game, with Ryan Nelsen and young full-back Adam Smith, on for his debut, deputising in the second half.
In the end, goals from Emmanuel Adebayor and Jermain Defoe were enough although Fulham impressed and Brad Friedel was forced to make four fine saves to hold onto his 14th clean sheet of the Premier League campaign.
“It was a tough game,” said Harry. “Fulham are a good side and played some good football.
“We were a bit patched up as well, no left-backs, Younes was struggling with his knee, Ledley wasn’t fit again, Kyle was hobbling around.
“Gareth had to start at left-back, he did great for us. I brought Jake Livermore back in to play with Sandro and they were solid in midfield.
“We lost a couple of players during the game and that made it difficult. Young Adam Smith came on and did well and it was great for him to be involved.
“William Gallas was back with Younes, then Ryan Nelsen came on, a fantastic professional. Brad Friedel pulled off a couple of saves when he had to.
“All we could do was win the game and that’s what we did.”
