Arsenal captain Thierry Henry has praised Denilson for quickly adapting to the English game.
The 19-year-old Brazilian has comfortably settled into the Gunners side following his move from Sao Paulo at the end of August and featured in their 1-0 FA Cup fifth-round replay defeat at Blackburn on Wednesday.
"I have never seen in my years here a player who has developed so quickly to the English game as Denilson," Henry said.
"He comes from the Brazilian league where the game is much slower and to acclimatise this quickly is amazing - and especially to do this in the midfield, where in England there is always so much pressure, but he already seems to have so much time."
Arsenal boss Arsene Wenger has had no problem in fielding Denilson and his young counterparts in the domestic knockout competitions and currently has a number of first team regulars on the sidelines, including Henry who has a foot problem.
But the Frenchman agrees with the manager's policy of fielding his emerging players.
"In every game, we show character and it does not matter who is playing," he continued.
"At Bolton I was not playing or Cesc (Fabregas), or Jens (Lehmann) or the lads who are injured - but it did not matter because we showed we have a collective character.
"This year in particular we have a really great squad. Whoever is in the team from this squad, you feel you are going to win. Whoever is in the team - I have no fear."
Wenger added: "What these boys have done against Liverpool, Everton, Tottenham and Chelsea on Sunday is not a coincidence.
"To repeat top-level performances is never that, and that is why I have complete confidence in them.
"Overall it is a very positive experience."
