Coventry City have completed the signings of Gustavo Hamer and Julien Dacosta following the Sky Blues' promotion from League One.

Hamer, previously an U-20 international for the Netherlands, became the first signing to join the West Midlands club this summer, arriving from Dutch side PEC Zwolle for a fee of around £1.5million. 

The 23-year-old central midfielder has agreed a three-year contract with the League One champions, after making 25 appearances for Zwolle in the Eredivisie last season. 

"He's a creative, two-footed midfielder with great technical ability," said City boss Mark Robins.

Robins added: "He's a quality addition to our squad ahead of our return to the Championship, a player our recruitment team have been monitoring closely for some time."

Since joining the Sky Blues, Hamer told supporters to “expect a lot of hard work from me, I’ll do my best and I’ll do my best for the team and the club.”

Versatile French full-back Dacosta became City's second signing of the summer, joining the Sky Blues from Ligue 2 club FC Chamois Nirot. The 24-year-old made 80 appearances for Les Chamois since departing Olympique de Marseille in 2017.

Upon Dacosta's arrival, Robins said: "Julien is a player we've been monitoring for some time now.

"He's a pacy and powerful defender, who also brings attacking attributes to the side."

Speaking to the club's website, Dacosta said:

”'I’m happy to have signed for Coventry and I'm in a hurry to wear the Sky Blue jersey in the Championship and make the support proud."

On January 9, Robins told BBC Coventry & Warwickshire that the League One champions are hoping to strengthen their striking options before the start of the 2020/21 season. 

Coventry's promotion to the Championship was confirmed last month, after clubs from League One and League Two voted to curtail the 2019/20 season due to the Covid-19 pandemic.
