Colchester United have completed two signings this afternoon, with striker Denny Johnstone recruited from Birmingham City, and teenage winger, Courtney Senior, snapped up from Brentford.

Scotsman Johnstone is a 6ft 2ins front-man who spent last season on loan in the Scottish Championship at Greenock Morton.

The 21-year-old has arrived for an undisclosed fee.

Senior, meanwhile, is an 18-year-old winger who has been signed on a free transfer.

Both have signed two-year deals.
