The Gunners look set to tie up the arrival of the Chilean attacker by the end of the week after beating Liverpool and Juventus to the punch, while the Newcastle right-back is also expected to make the trip to north London soon with an agreement understood to be in place between the Londoners and Newcastle.
Arsenal led the way in the league for the longest period of time, 128 days, of any side last season, but their early campaign form tailed off after Christmas as they slipped into a battle to cling onto fourth spot.
But Edu, who made over 100 appearances for the FA Cup holders, winning two titles along the way – believes that quality additions such as Sanchez and Debuchy will be enough to ensure that his old side can finish the season at the top of the pile:
“Arsenal are still in my heart and I still follow Arsene Wenger. I have a big relationship with that club.” He told talkSPORT.
“If they sign them [Alexis Sanchez and Mathieu Debuchy] of course Arsene Wenger is very clever.
“Everybody knows he is good at signing players, particularly young ones, and they can give good things to Arsenal and make them better and stronger as they look to win the Premier League.”
