Bruno Fernandes’ stunning volley salvaged a point for Manchester United at struggling West Brom, but Ole Gunnar Solskjaer’s side lost further ground in the Premier League title race.
United moved back above Leicester in second place, but are now seven points behind leaders Manchester City, who also have a game in hand.
The Baggies took a shock lead after just 83 seconds as on-loan striker Mbaye Diagne outmuscled Victor Lindelof to head in from Conor Gallagher’s cross.
United were finding it difficult to make inroads in a lacklustre opening period until Fernandes hooked Luke Shaw’s cross into the top corner with his weaker left foot.
Pierre-Emerick Aubameyang scored a superb hat-trick as Arsenal ended their three-game winless run with victory over Leeds United at Emirates Stadium.
Aubameyang opened the scoring in the 14th minute before doubling his side’s advantage from the spot towards the end of the first half.
Right-back Hector Bellerin grabbed a third on the stroke of half-time, with Aubameyang completing his hat-trick with a header moments after the restart.
But from 4-0 down Leeds grabbed two second-half goals through Pascal Struijk and substitute Helder Costa to give Arsenal a late scare.
Danny Ings scored in the 25th minute to give Saints a 1-0 lead, and Hasenhuttl’s men comfortably held the advantage until Wolves were awarded a second-half penalty when Ryan Bertrand blocked Nelson Semedo’s attempted cross with his arm.
The point of contention was whether the left-back’s arm was in an unnatural position. The VAR team, led by official Martin Atkinson, saw no need for the on-field referee to reconsider his initial decision to award the kick.
Ruben Neves scored from the spot before Pedro Neto produced a dazzling winner for the visitors.
The door looked wide open for Everton to make a big statement about their top-four credentials, but Carlo Ancelotti’s side produced a dismal display against Fulham who claimed a first league win since November.
Fulham’s Nigerian striker Josh Maja scored his first two goals for the club to rekindle their hopes of avoiding relegation, although they are still in deep trouble.
Scott Parker’s third-bottom side are seven points behind 17th-placed Newcastle United and the safety zone, with West Brom a further five behind and Sheffield United 14 adrift.
“I know what we need to do and the players do too. We can’t control what is around us, we just need to win football matches. If we do that I know it will be OK,” Parker said.
Everton boss Carlo Ancelotti said Wednesday’s 5-4 FA Cup fifth round win against Tottenham in extra time had taken its toll but praised Fulham for a deserved victory.
