Malik Mothersille has left Chelsea for Peterborough United.
The 19 year-old striker joins Posh on a two-year contract and for an undisclosed fee.
Mothersille rejected a new contract offer from Chelsea over the summer.
Posh manager Darren Ferguson said: "There is no pressure on Malik whatsoever, he is someone for the short, mid and long-term.
"He hasn't had much of a pre-season so we need to get him up to speed."
