Newcastle United are reportedly lining up a summer move for unsettled Manchester United left-back Luke Shaw.

The Red Devils defender was substituted off at half-time in his side's FA Cup quarter-final win against Brighton and Hove Albion on Saturday after failing to impress manager Jose Mourinho, who publicly criticised him – not for the first time – post-match.

Magpies manager Rafa Benitez tried to bring the 22-year-old to St James' Park on a loan deal until the end of the season during the January transfer window as he looked to provide Paul Dummett with more competition at left-back, but a move failed to materialise as Mourinho held on to a player that had forced his way into the XI in December and through into 2018.

A summer exit may well be on the cards now however, although he may not be the only player making his exit from Old Trafford.

Goalkeeper Sergio Romero has once again had to settle to playing second fiddle to David De Gea between the sticks, and if he was to leave it would surely catch the attention of Benitez, who has endured all sorts of problems in the goalkeeper departments since he took the reins at St James' Park – despite the success of January addition Martin Dubravka in recent weeks.

Here are three reasons Newcastle must forget Shaw and sign the Argentina international instead…

Romero joined Manchester United in the summer of 2015 but he has made just 37 appearances in all competitions for them since then, with six of those coming in the Premier League.

Considering he is an Argentina international who is now 31 years of age, the stopper will surely be thinking that he wants to play regularly again sooner rather than later, and he probably wouldn't be short of offers if he did choose to leave the Red Devils.

Benitez has been looking for an established number one since the start of last summer's transfer window, and there is no doubt that Romero could effectively fill the void.

While the Slovakia international has come in and impressed – especially in the 1-0 win against Manchester United at St James' Park last month – and looks set to join the Magpies this summer following the end of his loan spell, few could argue that Romero wouldn't be an upgrade on the 29-year-old.

The Argentina international has shown time and time again the qualities he has between the sticks and he has kept 24 clean sheets in 37 appearances for the Red Devils, conceding just 16 goals.

If Benitez wants more competition and quality in the goalkeeping areas then he should look to bring both to Tyneside, and let them fight it out for the number one jersey.

With 138 appearances across the Eredivisie, Serie A and the Premier League – along with 93 caps for Argentine – it is clear to see that Romero is hugely experienced and could add so much quality and know-how to the Newcastle squad.

If the Magpies secure their top flight status for another year – something that will be looking very likely should they beat Huddersfield Town at St James' Park on March 31 – Benitez will want to start the push for the top half of the table and eventually for Europe, and bringing players like the 31-year-old to Tyneside would only benefit the club in achieving those aims.
