Connolly will continue his development with Wigan Athletic after completing a season-long loan move to the Championship club.
Introducing the Everton Mishmash!
The 20-year-old pair both impressed out on loan in the Championship last season. Attacker Dowell scored 10 times in 43 appearances for Nottingham Forest, while Connolly played 36 matches for Ipswich Town and struck four goals.
Dowell and Connolly were both integral to England Under-21s’ Toulon Tournament success in the summer, 12 months after winning the Under-20 World Cup with their country.
