Blackpool sign Scott Robertson from Dundee United

Blackpool have completed the free signing of midfielder Scott Robertson on a two-year contract.

The 27-year-old began his career at Dundee before a controversial switch to cross-city rivals United in 2008.

Robertson, twice capped by Scotland, becomes Ian Holloway's fourth summer signing after Tiago Gomes, Isaiah Osbourne and Jake Caprice.

Striker Craig Sutherland however will miss the season ahead after suffering a serious knee injury.

The 23-year-old joined the Tangerines last summer after playing college football in the United States but only eight appearances before a loan spell at Plymouth.
