Aaron Ramsey joined Arsenal from Cardiff in 2008 but he was merciless on the first visit to his boyhood ground as he scored a double in Arsenal's classic victory on Saturday.
Manager Arsene Wenger wasn't short of praise. He told BBC Sport: "He was phenomenal. He keeps surprising me. He has matured as a player and as a person."
The Frenchman believes his 22-year-old midfielder costs five times the price he was brought by in 2008 - pumping the Welshman's price tag to £50 million.
When challenged whether he would part ways with the young midfielder had an offer in the extent of £50 million arrive, the boss stood firm.
"No. We don't want to sell anybody," Wenger told reporters.
He added: "We want to just keep our team together. I suffered enough from having to sell the players, no? And now we are in a stronger position financially, so we are not out there to sell our best players."
But the Frenchman also insisted Ramsey had enough room to improve.
"He can defend, he can attack, he can score goals. What do you want more?
"And he's young! That shows you that he can develop still more. When you look at his improvement in the last two years, why should he stop now?"
It seems like Wenger has the right to pose such a rhetorical question. Ramsey is Arsenal's top goal scorer and has created most chances in the Premier League and has most tackles too.
The Wales international has been instrumental in the Gunners' charge to the top by by scoring eight times in his 13 league appearances so far this season.
