Arsenal remain confident of signing Youri Tielemens from Leicester City.
The Gunners may have missed out on another midfielder this summer.
Their rivals Tottenham are close to securing a deal for Yves Bissouma from Brighton, who was also linked to Arsenal.
However, CBS Sports states that Arsenal are helped by this transfer.
The source claims that Spurs may have also gone in for Tielemans, but have now found their new midfield signing.
He tweeted: "Arsenal remain confident and on course to sign Youri Tielemans before the month is out. Interest from Tottenham was never too advanced.
"But Bissouma's incoming arrival will allay fears Spurs could hijack the deal. Tielemans is one of Arteta's top priorities."
