Arsène Wenger believes it would be "impossible and not responsible" to concentrate on qualifying for next term's Champions League solely by winning the competition this season.
Arsenal have two routes into Europe's top event in 2006/07. They can either finish fourth in the Premiership or beat Villarreal in the Champions League Semi-Final and then Barcelona or Milan in the Final to qualify as holders.
It has been argued that the second method will be easier - after all it involves three wins rather than the probable six they require in the Premiership. However the manager dismisses the concept.
At his pre-match press conference ahead of the game with Portsmouth, Wenger was asked if it would be simpler just to go 'all-out' in the Champions League.
"It's impossible," he replied. "It would not be responsible as well.
"I feel we can combine both," he went on. "We can do very well in the Champions League and finish fourth.
"It depends on how well we do in these kinds of games [tonight] and how much we 'switch on'.
"Both are massive challenges. I would say the Champions League is of course the most glamorous one and the present, but the future for us is the Premiership."
