Arsenal boss Arsene Wenger says Southampton deserve credit for Theo Walcott's development.
Wenger says the credit should be shared between the two clubs.
"The real question is at what age can you think you have produced a player?" he said. "For me he has been educated at Southampton [but] I consider today that a top, top, top Premier League club produces a player when it takes them at 16 and is bold enough educate him and play him in the Premier League.
"He had no starts in the Premier League - he went to the World Cup [in 2006] without any starts in the Premier League [so] it's a question that is quite open.
"It is a combined education from Southampton and Arsenal. That is how you can basically call it."
