Snachez dismisses Arsenal exit talk

Chile international Sanchez reacted angrily to being substituted after concluding the scoring in the Gunners' 4-0 win at Swansea City on Sunday (AEDT), but Wenger suggested his Stamford Bridge counterpart Antonio Conte has far greater concerns with his own star striker.

Costa sat out Chelsea's 3-0 triumph at Leicester City on the same day, when the leader extended its advantage at the summit to seven points.

The official reason for his absence was a back complaint, but the Spain international's exclusion came amid reports of a training ground row with Conte, framed by speculation that Costa is the subject of a mega-money offer from Chinese Super League side Tianjin Quanjian.

"I'd rather have someone who always wants to be involved than someone who doesn't want to play," Wenger said.

"I have enough problems —I don't need a Costa problem on top of that.

"Alexis is a guy who wants to fight everywhere, sometimes where he shouldn't. But that is a part of his game. All my players want to play for every minute but for me this is not a story."

Tottenham made its case for being Chelsea's sternest title rival by extending its winning run to six Premier League matches in emphatic fashion, dispatching West Brom 4-0.

Spurs manager Mauricio Pochettino gave his take on the Costa situation and was happy to report no similar rumblings of discontent at White Hart Lane.

"Have there been any offers from China for my players? No," he said.

"My reaction to the Costa story was indifference because, luckily, it is not my problem.

"What can you do when an offer like this arrives from a country that is like this?

"It's crazy money. It looks like they broke the market. If the offer to Costa is true, it's unbelievable, unbelievable. But we will see what happens."

Pochettino said: "We are together, every player is happy and part of our Tottenham family, and we have a very good atmosphere around the club."
