England will bank on James Anderson transferring his renowned skills from Trent Bridge to Lord's this week - but coach Andy Flower insists his attack is no one-man band in any case.

Anderson was a class apart in Nottingham, where he took the last four Australia wickets to finish with 10 in the match and help deliver England's 14-run win and a precious 1-0 lead after a classic Ashes Test.

So to Lord's on Thursday for the second instalment of the Investec series, when England must decide whether to persevere with the out-of-sorts Steven Finn as their third seamer or bring in either Tim Bresnan or Graham Onions to support Anderson and Stuart Broad.

Whatever their choice from the unchanged 13-man squad confirmed on Tuesday morning, Flower is at pains to point out there is much more to England's bowling than the Lancastrian who has made a corner of Nottinghamshire his own - with a record 49 wickets in his seven Tests there.

"When you've got great players in your side, they will affect games - but a lot of our guys stood up and performed well in this match," he said after England had sneaked the first-Test verdict. "It's not one man performing."

No one could sustain a counter-argument after 10 more wickets England needed in the first Test were shared among their other three frontline bowlers and part-timer Joe Root.

Finn was conspicuous by his absence from captain Alastair Cook's deployment while the tireless Anderson was bowling 13 successive overs with the old and then new ball as England resisted Australia's fightback on the final morning.

But Flower said: "Steven Finn took crucial wickets in that first innings. We only had just over 200 on the board, and he got (Shane) Watson early and (Ed) Cowan first ball. Those were crucial breakthroughs for us.

"That sort of striking is one of the things he's capable of with pace and bounce. He also bowled a really skilful spell of reverse-swing against (Michael) Clarke and (Steve) Smith - beautiful outswing, and almost got an lbw with inswing. So he made his contribution to this game as well."

Flower retained the faith throughout that England would prevail, even as Brad Haddin's defiant 71 was taking the outcome well out of everyone's comfort zone.

"Obviously, they'd fought back brilliantly ... it was an amazing game of cricket," he added. "Well done to them for getting that close. But I always believed we could create enough chances to win that game."

The coach saw no reason to reproach Broad for his controversial refusal to walk after edging a ball to slip in England's second innings.

"When I played cricket I didn't walk when I'd edged it, so I'd be a hypocrite to say that all other players should walk," said Flower. "Most players leave it to the umpires to make the decision, and I don't think there's anything wrong with that."
