Heurelho Gomes hopes his fantastic form will help Tottenham finish fourth in the top-flight as well as earn him a place in Brazil's World Cup squad.
The goalkeeper earned the plaudits when pulling off great saves to deny the returning Robin van Persie and Sol Campbell during Spurs' crucial 2-1 victory over Arsenal on Wednesday.
But Gomes knows Harry Redknapp's side must build on that result against Chelsea on Saturday to keep up their push for the last coveted UEFA Champions League spot.
He told the Daily Mirror: "We have to keep going. Beating Arsenal gives us more confidence but we had that before this game anyway.
"We know we've to win games to try to finish in the top four. Now we have Chelsea which is another massive game.
"They have a couple of players injured but still have a good squad."
While Gomes has won nine caps for Brazil, the last came back in 2006. The Spurs keeper now hopes his good form may earn him a call-up into Dunga's squad.
He added: "I hope so. I think Dunga watched the game and I hope to keep going like I am now and try and do my best to make the World Cup squad."
