The England international was the subject of a rejected loan offer from the Bundesliga giant at the weekend, but it has returned with a cash bid for the 33-year-old.

However, the Magpies have no intention of selling Trippier, who joined the club from Atletico Madrid in January 2022, during the current transfer window.

They have also rebuffed an approach from Atletico for striker Callum Wilson on loan and signalled that they want to keep him at St James’ Park for at least the remainder of the season as well.

Al-Shabab – not one of the four clubs in which Saudia Arabia’s Public Investment Fund, which holds an 80 per cent stake in Newcastle, has a controlling interest – is also chasing Paraguay frontman Miguel Almiron, but is yet to reach a point where his current employer would even have cause to think about a deal.

The knowledge that the Tyneside club is close to its spending limit after a £400 million-plus ($771 million), two-year recruitment drive appears to have prompted suitors to test the water this month.

While chief executive Darren Eales has admitted that player trading is something the club will have to do in the longer term, there is no great willingness to start now with injuries continuing to deplete head coach Eddie Howe’s squad, and none of the players in question are agitating for a move.

Bayern, which has other targets, now faces a decision over whether or not to consider their pursuit of Trippier before the 1 February deadline, knowing that it may have to go significantly higher than its valuation if it is to spark a rethink.
