The 21-year-old – who moved to Tyneside from Tenerife over the summer – has been a revelation since breaking into the Magpies’ first-team during the poor run under Alan Pardew at the start of the season, and has since notched five goals in 19 appearance – albeit only 11 of these have been from the starting XI.
His form has also been recognised internationally with a call-up to the Spanish U-21 side, which was built on his fine form in the second tier last season.
And his continued importance to Newcastle of the Christmas period has now attracted some of the ‘big boys’, with Arsenal and United weighing up offers.
The pair have been impressed by his showings in the black and white shirt, with his nimble footwork, agility and eye for goal all big factors.
The managerial uncertainty at St James’ Park is also a boost, with Pardew having not been replaced since taking the Crystal Palace job last week.
The North East side are known for their willingness to sell star names, and a quick profit on the £2m paid a matter of months ago may temp controversial club owner, Mike Ashley.
