A select round-up of all the day's transfer news and rumours regarding the Magpies.
The 36-year-old, who has spent the majority of his career in the German Bundesliga, was released by Hamburg at the end of last season.
The Magpies have been linked with a move for the man who won over a century of caps for Croatia, but it is claimed that fellow relegated side Aston Villa could rival them for his signature.
The 19-year-old was a key figure for the Saddlers last term and was one of three nominees for the Football League Young Player of the Year award.
His form has reportedly seen him attract interest from the likes of West Ham United and Leeds United, but Rafael Benitez is thought to be interested in the player, who could cost as little as £1.5 million.
Armstrong scored 20 goals in 40 League One appearances for Coventry City last season, form which has seen many magpies fans call for his integration into the first-team squad at St. James' Park.
The midfielder, who scored 11 goals in his first Premier League season last term, looks likely to end up at Anfield with the Mirror reporting that Tottenham have bowed out of the chase, but the Reds will have to pay a premium for the Netherlands international.
It has been suggested that Benitez could look to bring in a Liverpool player on loan as part of any deal.

The French club are thought to be keen on a season-long loan deal, but it is suggested that the Magpies will only agree to that structure if a clause is inserted which obligates the Ligue 1 side to make the move permanent for that fee in a year's time, something which could price Marseille out of a deal.
Moussa Sissoko's protracted exit saga has also taken another turn with the French midfielder having revealed in a widely-cited interview with France Football magazine that he is keen to play Premier League football again this season.
Sissoko had been linked with German side Borussia Dortmund, but it appears as though he is angling for a move to one of his reported English suitors, a list which could include the likes of Arsenal, Liverpool, and Tottenham Hotspur.
