Analysis – what to expect
An intriguing local derby kicks off Round 21 of Super League with league leaders Castleford travelling to Wakefield. Trinity have been impressive this season and are worthy of their current league placing but are desperate to finish inside the top 4. Cas have been even more impressive and already look set to claim the League Leaders' Shield in 10 games' time. The Tigers have been too good for Wakefield in recent meetings, winning by an average of a 30 point margin in their last six league games. Whilst that margin may not be reached in this fixture, Castleford should again have too much for Wakefield.
