The summer transfer window has come to an end and Aberdeen have announced five new signings in a row. The club's defense and attack have been strengthened with the arrivals of three centre-backs and two forwards.

The first signing is defender Ryan Jack, who comes from English Championship side Middlesbrough. Jack is a versatile player who can play at both centre-back positions. He joins the Dons after spending time on loan at Celtic and is expected to provide a solid defensive presence for the team.

Next up is goalkeeper Craig Gordon, who has joined from Scottish Premier League side Hibernian. Gordon is a reliable shot-stopper and will be crucial to the team's success this season.

Defender Scott Brown also arrives from Hibs, bringing experience and leadership to the squad. He is another key addition to the defense, and will be a big asset as the team looks to defend their league title.

Midfielder Cameron McGeehan completes the trio of new signings, coming from the Irish Super Cup winners St. Patrick's Athletic. McGeehan is a creative midfielder who can link up well with his teammates, and will be a valuable addition to the midfield.

Finally, forward Joe Mathewson rounds out the list of signings, joining from Belgian Pro League side K.S.C. Lokeren. Mathewson is a prolific goalscorer and will be a threat going forward for the team.

These new signings have bolstered the team's defense and attack, and should help them achieve their goals this season. With a strong team in place, the Dons are looking to make a push for promotion and challenge for the Scottish Premiership title.
