you are saying this with hindsight, my statement is pertaining to the year 2009 when those two players signed their contract raises. In 2009, those players would have got nice raises elsewhere. You have to remember that Denilson played pretty good at 21 years old for a side that made the CL semifinal and was a top 4 side in hte premiership. Bendtner was rumored to have interested clubs like Bayern, Inter, and Milan before we gave him the new contract.
now this is an entirely different conversation, the club did (maybe still does) offer bigger wages to guys who are teenagers. I remember Traore was all set to move to Benfica, but Benfica wanted to only offer half the wages Arsenal were paying him. I think he was on 624,000 a year, and Benfica wanted to offer 300,000 a year. Ramsey is another example of that.
