Everton have reportedly been put on red alert over fears that young forward Ademola Lookman wants to return to London.
The 19-year-old made a strong impression in the second half of 2016-17 after joining from Charlton Athletic, netting on his first top-flight outing in the memorable 4-0 win over Manchester City.
According to The Sun, however, Lookman is tempted to leave Goodison Park and return back to the capital after being used sparingly so far this season.
Arsenal are said to have been tipped off that the England Under-21s international wants out, with the Gunners seeking some additional pace out wide.
Lookman, originally linked with a move to the North Londoners last year, is understood to be valued at £15m - £4m more than Everton paid to sign him from Charlton in January.
