Liverpool, England, (AP): Virgil van Dijk scored a late winner against West Ham on Sunday to move Liverpool to within six points of the Premier League title.

A 2-1 victory at Anfield means Arne Slot's team needs to win just two more games to be certain of a record-equaling 20th English league title to draw level with Manchester United's total.

Liverpool had looked like they were dropping points when Andrew Robinson scored an own goal in the 86th minute to level the game at 1-1 after Luis Diaz's opener. But captain Van Dijk rose to head home in the 89th and ensure the league leader took advantage after second-placed Arsenal slipped up on Saturday by drawing 1-1 with Brentford.

Chelsea came back from 2-0 down against relegation-fighting Ipswich to draw 2-2, and Wolves’ hopes of avoiding the drop were further boosted by a 4-2 win against Tottenham.

The Wolves moved above West Ham on goal difference and up to 16th in the standings. Both teams need five more points to be certain of safety.

Liverpool could be crowned champion as early as next Sunday if Arsenal loses to Ipswich earlier that day.

The Merseyside club is 13 points clear at the top of the standings with six rounds to go.

Victory completed a week of celebrations for Liverpool supporters after top scorer Mohamed Salah ended uncertainty over his future by signing a new two-year contract.

He marked that new deal in style by maintaining his outstanding form this season to cross for Diaz's opener in the 18th minute.

It was his 45th goal or assist in the league this season, which set a new record for a 38-game Premier League campaign, according to statistician Opta.

He left the field late on to a standing ovation from the home fans.
