[Getty Images]Rob Edwards needs a win. The Wolves manager has done a lot to revive the unity which had been lost at Molineux earlier in the season, but that is in danger of disappearing during an end-of-season drop-off.Victories against Aston Villa and Liverpool, and a battling point after being 2-0 down against Arsenal, raised expectations and showed there was still fight in this Wolves team.They were going down swinging two months ago - and also fought back from 2-0 behind to claim a point at Brentford - but three straight defeats without scoring to West Ham, Leeds and Tottenham had seen optimism evaporate.A poor draw against a Sunderland side playing for more than an hour with 10 men did Edwards no favours.Wolves were booed off at the end, while his decision to replace Hugo Bueno with Angel Gomes late on was also jeered.Some fans need convincing Edwards, who joined from Middlesbrough in November, is the right man to mount a promotion challenge next season as Wolves target a return to the Premier League at the first attempt.He has won five of his 26 games in all competitions - losing 15 - but still needs time to get to grips with a squad which needs major surgery and faces a big overhaul this summer.Wolves host Fulham in their final home game on 17 May and victory is imperative to ease fans' growing doubts about their manager.
