Champions League football, Cole Palmer and having the youngest squad in the Premier League were three of the reasons that helped Chelsea beat a host of other clubs to sign Liam Delap.
Manchester United, Everton, Nottingham Forest and Newcastle all showed strong interest in the England Under-21 striker after a £30m release clause was activated following Ipswich's relegation from the Premier League.
Manchester City had a buy-back option after selling Delap for £20m last summer, but opted not to use it.
Earlier this month, Delap was given permission by Ipswich to speak to several interested clubs.
