Mick McCarthy has said that Tyrone Mings proved why Ipswich Town were so keen to keep him this summer with his display in the victory over Brighton & Hove Albion.
The 21-year-old played a starring role as the Tractor Boys won 2-0 on Tuesday to record their second Championship success at Portman Road in four days.
Ipswich apparently rebuffed transfer deadline day interest in Mings, who Ipswich signed from non-league Chippenham Town in 2012, and McCarthy is delighted with how the left-back is developing.
He told reporters: "Tyrone showed why I wanted him in my team, why I wanted him at this club, and why he wasn't for sale.
"He wasn't going anywhere and no amount of euros or pounds was going to make a difference. We picked him up from relative obscurity and helped him become a player. Now I want him to help us become a good team."
He added: "It has been a good few days and a good haul from two home games."
Mings made only four Championship starts last season, but is now first choice following the sale of Aaron Cresswell to West Ham United.
