Dundee United travel to Pittodrie tomorrow for the last 'New Firm' derby of the season, knowing that a win is vital to keep up their challenge for European football next season. With The Terrors one point behind third placed Motherwell every game is vital now for Craig Leveins side. Aberdeen meanwhile are in with an outside chance of European football next season but must rely on other teams to get results for them.

Dundee United have the edge over Aberdeen this season, playing four in all competitions, winning three and losing one, inflicting two particularly heavy defeats along the way:

League Cup Aberdeen      1-4 Dundee United
SPL        Dundee United 3-0 Aberdeen 
SPL        Aberdeen      2-0 Dundee United
SPL        Dundee United 1-0 Aberdeen

With defenders Lee Mair and Zander Diamond missing through injury and suspension along with other absentees Darren Mackie, Richie Byrne and Jamie Smith, on-loan defender Alan Maybury’s injury adds another challenge to Calderwood’s plans for tomorrow.

But while third spot in the SPL is still a possibility, Calderwood’s focus is firmly on next season following the expected departure of six players from the Pittodrie side. Having signed Oldham’s former Kilmarnock midfielder Gary McDonald on a pre-contract, he is hoping to have more new recruits secured before the end of the campaign. Dutch youngster Dyon Camero has impressed in his short trail. The 19-year-old FC Zutphen forward will go back to Holland on Sunday, but could return.  Aberdeen defender Alan Maybury’s suspected fractured rib could rule him out for the rest of the season but it will not affect his chances of securing a permanent move to Pittodrie. The on-loan Leicester City player'sloan deal runs out at the end of the campaign, as does his contract at Leicester, but Dons manager Jimmy Calderwood is hoping to make the Republic of Ireland international an integral part of his squad for next season.

Prediction: Aberdeen are unbeaten in their last seven home games, and have not drawn in their last five, whilst United have not win away in three and drawn their last three games.  A tight home win for Aberdeen.
