“I understand the stature of this club and can see the trajectory it is on with these players and the head coach,” said Delap.

“It’s going to be an incredible place for me to develop, and I hope to achieve amazing things here and help the club win more trophies.”

Delap scored 12 goals in 37 top-flight appearances last term.

The Englishman emerged from Manchester City’s academy and had loan spells at Stoke, Preston and Hull before joining Ipswich in 2024 for about £20m.

Delap said he would “never forget” his time at Portman Road.

He added the support of boss Kieran McKenna and the fans meant Ipswich was “the perfect environment” for him to gain Premier League experience, having made just two top-flight appearances with Manchester City.

The son of former Republic of Ireland international Rory Delap, he was at Derby County’s academy before joining City’s academy as a teenager.

He made six first-team appearances for City, scoring once in the League Cup, before loan spells followed and a permanent switch to Town.

Chelsea, who won this season’s Uefa Conference League, have qualified for next season’s Champions League, which gives Delap the chance to add to his solitary appearance in the competition with Manchester City in 2022.

Delap is part of England’s training squad for the European Under-21 Championships in Slovenia later this month, but is now likely to miss the tournament.

Chelsea are involved in the Fifa Club World Cup, which takes place from 14 June-13 July in the United States, and the extended competition takes priority over the U21 Euros.

The Blues finished fourth in the Premier League but struggled for goals in the competition from a recognised centre-forward, with Cole Palmer top scorer on 15.

Nicolas Jackson scored 10 in 30 league appearances, Christopher Nkunku had three in 27 and teenager Marc Guiu did not find the net in his three matches.
