Wilkins was an assistant manager at Chelsea under Luiz Felipe Scolari and Carlo Ancelotti.
Former Chelsea assistant manager Ray WIlkins is impressed by the club's transfer business, and expects more new arrivals at Stamford Bridge before the season starts.
Blues boss Jose Mourinho has already brought in Cesc Fabregas from Barcelona and Atletico Madrid's Diego Costa this summer, with Costa's former teammate Filipe Luis set to sign this week.
Chelsea icons Frank Lampard and Ashley Cole have departed the club and David Luiz was sold to Paris Saint-Germain.
But Wilkins, who began his playing career at Stamford Bridge before two stints as an assistant manager, believes the Blues have a stronger squad than last season.
"The loss of Frank Lampard and Ashley Cole was a big loss to Chelsea," he told Sky Sports News. "But Fabregas has come in, Diego Costa has now come in and they have just taken Luis from Atletico Madrid, so there's the left-back spot secured."
"[Mourinho] now has reinforcements at centre-half with Ivanovic because Azpilicueta will probably play at right full-back. [Nathan] Ake is being groomed as a left full-back but can play anywhere, he's an extremely talented young man and I would like to see him come through this year."
"I definitely think he has strengthened the squad and I don't think that's the end of it either, I think he'll bring in more."
Chelsea have been linked with moves for the Real Madrid pairing of centre-half Raphael Varane and Sami Khedira in the past week as Mourinho looks to build a title-winning squad.
They will face stiff competition from their Premier League rivals, however, with Manchester United eyeing Varane and Arsenal in for Khedira's signature.
