Newcastle United are considering a move for Jefferson Montero if they miss out elsewhere, according to claims on Sunday morning.
Atsu signed on in May, converting his loan to a permanent deal, but only defender Florian Lejeune has been added since then.
Jefferson Montero is yet another tricky winger with pace that Newcastle are linked to – but also another who has a dubious end product.
Joining Swansea from Mexican side Morelia in summer 2014, Montero signed a four year contract, meaning that he now has only another 12 months to go.
Swansea paid around £4m three years ago and The Sun say that the Welsh club are happy to let the winger go if they recoup around the same figure.
Jefferson Montero turns 28 in September but has never really pinned down a permanent place in the first team at Swansea, making 15 starts and 15 appearances off the bench in his first (2014/15) season and then 14 and 9 in his second (2015/16) season.
Recurring hamstring problems then added to his problems last season, making only 2 Premier League starts and 11 off the bench.
A regular for Ecaudor, he has over 60 caps for his country.
That first season in the Premier League saw an impressive return of seven Premier League assists and one goal, despite only 15 starting elevens.
However, he has only then managed three assists and no league goals in the last two seasons.
Any signings Newcastle make are bound to have some doubts attached but whether it is is Montero or whoever, the hope would be that Rafa Benitez can get the best out of them.
