Henrik Larsson is determined to build on his impressive debut for Manchester United.
The on-loan striker hopes to maintain his momentum and retain his place in the side to face Aston Villa tomorrow at Old Trafford.
He said: 'I was happy with my fitness and sharpness but I can't get carried away because this was just one game. One swallow doesn't make a summer and I know I need to keep working hard and improving.
'When I play next is up to the boss (Sir Alex Ferguson), but whether I come on as a substitute or play from the start, I will be doing my best. This is very exciting. I just want to be able to play as big a part as possible while I'm with this great team.'
Larsson opened the scoring in the FA Cup victory against Villa at the weekend after being released by Wayne Rooney.
The Swede, who has joined on loan from Helsingborg, enjoyed his partnership with the young England striker.
'We had some nice little combinations and we were able to find each other at important moments,' said Larsson on his website. 'The goal was one of those. Wayne received the ball and at first I nearly ran into him.
'But I made some space so when the ball came to me I touched it and shot more or less in one movement. It was a lovely feeling as it hit the net.'
However, Larsson knows there is good competition for places up front.
Ole Gunnar Solskjaer is pushing for a place in the starting line-up after scoring the winner against Villa while Louis Saha could come into contention following a groin strain.
Ferguson is expected to recall goalkeeper Edwin Van der Sar, Nemanja Vidic and Paul Scholes after the trio missed the FA Cup clash.
The Old Trafford boss is expecting another difficult encounter from Martin O'Neill's side.
He said: 'It will be a tough game as Martin has them galvanised, no question about that.'
