Clyde have completed the signing of four trialists who have featured in most of their pre-season friendlies.
Roberts believes his players will take the league by storm
And they have also given a trial to released Morton striker Alex Williams, who is also reportedly wanted by former club Stirling Albion.
Clyde have signed former Ayr goalkeeper Peter Cherrie and former Gravesend & Northfleet defender Romuald Bouadji.
Kevin Bradley has re-signed, while fellow midfielder Andrew Dick has joined after leaving Falkirk.
The 19-year-old Dick started his career at Rangers and will be hoping for the regular first-team football that evaded him with the Bairns.
Cherrie, who impressed in the recent friendly against Manchester United, spent some time at junior side Kilsyth Rangers but also has senior experience with Airdrie.
Fellow 22-year-old Bouadji started his career with St Etienne but played on a regular basis in non-league football in England, becoming known to Clyde boss Graham Roberts during their time at Carshalton.
The 19-year-old Bradley broke into the Clyde first team last season.
Meanwhile, Williams, watched by Stirling boss Allan Moore, grabbed the opening goal as the Bully Wee completed their pre-season warm-up with a 3-2 win over Larkhall Thistle.
There was also a place in midfield for 18-year-old former Ipswich Town midfielder Fraser Beveridge.
