Atletico’s first priority is to completely overhaul the left flank, which has underperformed this season. On the wing, Villarreal’s Alex Baena has emerged as a serious option. Though Baena’s release clause stands at €60 million (£51m/$68m), sources suggest that Villarreal may be open to negotiating a lower fee. Atalanta's Ademola Lookman was also considered as a winger option, but the Serie A star is reportedly beyond their budget.
Central defence is another key concern for Diego Simeone’s side, and Atletico have reportedly initiated discussions with Tottenham over a possible deal for Cristian Romero. The Argentine has become one of Spurs’ most consistent performers, but prising him away won’t be easy or cheap. The north London club is said to have placed a €70m (£60m/$80m) valuation on the centre-back.
