IT has been a summer of change for Cambridge United ahead of their visit to Valley Parade tomorrow.

Colin Calderwood’s side have seen the usual comings and goings you would expect at a club in pre-season.

Summer additions include right-back Kyle Knoyle from Swindon Town, attacking midfielder Luke Hannant on a free transfer and striker Harvey Knibbs, who has signed a two-year contract after leaving Aston Villa.

Their main summer departures have been attacking midfielders Jevani Brown, who has joined Colchester United, and former Liverpool youngster David Amoo, who has gone to Port Vale. Right-back Brad Halliday has joined former Bantams favourite Darren Moore at League One Doncaster Rovers.

Former Spurs and Scotland defender Calderwood (pictured below right), who joined the U’s as head coach in December last year, will also be looking for a vastly improved term after Cambridge finished fourth-from-bottom in League Two last year. He tends to set up his side in a 4-4-2 or 4-4-1-1 formation.

Those who watch Cambridge on a more regular basis have commented that the defence has improved under Calderwood over the summer, but goalscoring remains a concern for them.

But they have boosted their attacking options this week with the capture of Andrew Dallas.

The 20-year-old joins from Rangers for an undisclosed fee following a two-week trial at the Abbey Stadium club.

He spent the second half of last season on loan at Scottish Championship side Morton, failing to score in 12 games.

Midfielder George Maris has re-signed for the club after knocking back a deal in the summer.

But Calderwod did confirm earlier this week that they did miss out on a deal for former Norwich City ace Wes Hoolahan, who is rumoured to be heading to play in Australia.

In changes off the field, Ian Mather has been appointed interim chief executive officer.
