Arsenal forward Theo Walcott has hailed the "fantastic" feeling of going back to the top of the Premier League table after their 3-1 win against West Ham United.

The Gunners staged a second-half comeback to beat the Hammers at Upton Park to regain top spot in the division, and Walcott described his happiness at going back to the summit.

"It feels fantastic, we wanted a nice positive away win today," Walcott told BT Sport.

"It's great to be top but it is so close and everyone can take points of each other, so we have got to look after ourselves.

"It was a great comeback today. We reacted in a great way [to going a goal down]."

Arsenal travel to Newcastle United on Sunday.
