The Real Valladolid defender posted a picture on Instagram revealing his location, H10 London Waterloo. It sent Arsenal fans into a frenzy with clearer links of a transfer move being set up as we approach the January window.
Calero is being closely monitored by Borussia Dortmund and Sevilla as well. His release clause is understood to be around £10m with his current deal set to run till the summer of 2021.
Arsenal are facing a probing issue in the centre-back position after Rob Holding’s season-ending injury last month.
