Harry Redknapp pointed to hard work rather than free-flowing football as the key to another vital away win at Blackburn on Saturday.
Peter Crouch's double secured maximum points and a fourth win on the road in the Barclays Premier League this season.
We had to fight all the way though. Rovers edged the first half in terms of territorial advantage without seriously testing Heurelho Gomes and we struck a huge blow in added time when Crouch headed home from Niko Kranjcar's cross.
Rovers tested us to the limit defensively at the start of the second half but we held on magnificently, Sebastien Bassong summing it all up when he got to the ball first to deny Franco Di Santo a tap in after Benni McCarthy's shot hit the inside of the post and rolled along the line.
Crouch secured victory with his second goal seven minutes from time, a clinical finish to a fine team move involving Vedran Corluka, Robbie Keane and Jermaine Jenas.
"It wasn't about a free-flowing performance," said Harry. "The conditions were difficult, we had sleet and snow coming down throught the game and Blackburn worked very hard.
"They worked hard as Sam's (Allardyce) teams always do, pressed us, closed us down and made it difficult for us.
"They had one or two opportunities as well and it wasn't an easy game, it was a tough game and we ground it out.
"It's a big win for us because Blackburn is always a tough place to go to. I came and watched them play Liverpool a couple of weeks ago and they were excellent that day, so we knew what to expect.
"It wasn't a classic, but everyone worked hard and it's a big three points for us."
