Millwall have signed teenage Arsenal forward Jay Simpson loan until January.The 18-year-old is a regular for the Gunners' reserves, and scored an FA Youth Cup hat-trick last season, but is still awaiting his first-team debut.
"Jay is a very promising young player - he is quick, strong and aggressive," Lions manager Willie Donachie told Millwall's website.
"He will add something to our squad, and I'm very pleased that we've managed to bring Jay in."
