Manchester City remain 10 points clear at the top of the Premier League as Raheem Sterling's early header was enough to beat Arsenal 1-0 on Sunday, while Jose Mourinho's Tottenham suffered another damaging defeat at fourth-placed West Ham.

Manchester United and Leicester are City's closest challengers as United saw off Newcastle 3-1 at Old Trafford and Leicester won 2-1 away to Aston Villa.

An 18th consecutive win in all competitions edged City ever closer to a third league title in four years, even if Pep Guardiola's men did not hit the heights they have in recent weeks at the Emirates.

Sterling could have scored three times inside the first five minutes, but his soaring leap to nod home Riyad Mahrez's cross secured all three points as City kept a 10th clean sheet in their last 13 league games.

"The people think it looks easy. This is so difficult," said Guardiola.

"I didn't expect this consistency in the past month. Winning in this period these games 1-0 is what we need."

In Italy, Inter Milan beat city rivals AC Milan 3-0 to extend their lead at the top of Serie A on Sunday (Feb 21) as Lautaro Martinez scored a double, with Romelu Lukaku also on target.

Inter opened up a four-point lead over their second-placed opponents as Antonio Conte's side target a first league title since their unprecedented treble under Jose Mourinho in 2010.

Lukaku was in top form, the Belgian playing a role in Martinez's two goals on five and 57 minutes before scoring his 17th goal in the league this season to move to the top of the Serie A scorers' chart.

Milan, chasing a first Scudetto since 2011, fell to back-to-back Serie A losses for the first time this season, with their title push suffering another blow with a fourth defeat in eight league games.
