Premier League: 3 talking points from the weekend action

The Premier League title race is on a knife-edge after Manchester City retained pole position with a pulsating 2-2 draw against their closest challengers Liverpool.

Antonio Conte's Tottenham revolution gathered pace with a 4-0 rout of Aston Villa that boosted their top four bid, while Leeds should be safe after an impressive win at Watford.

Here are three things we learned from the Premier League this weekend:

Prize fighters can't land knockout blow

Manchester City and Liverpool traded blows throughout an enthralling clash between the Premier League heavyweights, but neither could land the knockout punch that would have put them on course to clinch the title.

Leaders City sit one point clear of second-placed Liverpool after goals from Kevin De Bruyne and Gabriel Jesus were cancelled out by Diogo Jota and Sadio Mane.

It was the kind of high-quality contest that underlined why both sides can stake a claim to being the world's best.

Liverpool could cement that argument if they can pip City to the title, but Reds boss Jurgen Klopp knows the reigning champions will be tough to catch.

"It was an exceptional game of football. Two heavy-weights, chomping at each other. It's crazy the intensity. A completely different level," Klopp said.

"Both arms down for a second and you get a massive knock. Now we have to be as close to perfection to win seven Premier League games. Insane!"

Guardiola agreed with Klopp's assessment that only perfection will be enough to take the title, and he admitted it was frustrating not to kill off their rivals.

"He likes his punching games! No regrets, but I had the feeling that with this result we missed an opportunity, a feeling we leave them alive," Guardiola said.
