Monaghan's power a worry for McGuinness

Jim McGuinness says Monaghan's physical strength will pose a huge challenge to his Donegal players in the Ulster Football Championship final.

Donegal are aiming to complete a hat-trick of provincial titles in the Clones showpiece on 21 July.

Last season, McGuinness also guided Donegal to their first All-Ireland triumph since 1992.
