Ray Wilkins believes Chelsea need to make big signings this summer
Conte led Chelsea to the Premier League title in his first season in England, finishing seven points clear of London rivals Tottenham in second.
The Blues were beaten 2-1 in the FA Cup final by Arsenal last Saturday, preventing the Italian manager from claiming a historic double.
Chelsea completed their title feat without Champions League football but will be back in Europe's elite club competition next season.
Wilkins was disappointed with the defeat to Arsenal and says improvement to the squad is needed, as well as blooding some younger players.
