Arsenal manager Mikel Arteta has lauded Eddie Nketiah for his 'phenomenal' work-rate.

The 20-year-old found the back of the net in Monday's FA Cup fifth-round win over Portsmouth, his third goal since re-joining the club last month from a loan spell with Leeds United.

"He has been phenomenal," said Arteta.

"The workrate that he puts in, the rhythm that he goes into pressing, his understanding of the game - when to come and when to go in behind - and always in front of goal, he is ready to score."
