Millwall have secured Arsenal winger Jay Simpson on-loan to the end of the season.

The 19-year-old has proved a hugely popular figure at the Den since his initial loan spell began at the end of August, and has found the net three times in 20 appearances.

"I'm very pleased that he will be staying until the end of the season," said Lions boss Kenny Jackett.

"Jay is a very promising young player who I am sure will improve further during the second half of the campaign."
