Diego resigned with Atletico Madrid in January on a six-month loan deal to bolster the side’s squad ahead of a busy schedule. However, manager Diego Simeone is unlikely to extend the player’s deal which has put a number of other clubs on alert. Tottenham Hotspur and Arsenal are said to be interested, as too are Greek champions Olympiacos who are looking to add a player with European experience to next year’s squad. Fenerbahce, having recently wrapped up the Turkish Superlig title could offer the former Wolfsburg player a bumper deal to take him to Istanbul, according to Tutto Mercato. However, with Besiktas also have their sights set on a new midfielder and see Diego as a suitable fit in their team. The Brazilian has the opportunity to add a Champions League title to his name before he moves on, as Atletico face rivals Real Madrid in Lisbon on 24 May. Diego is not in Simeone’s long-term plans and is almost certain to leave when his contract expires on 30 June.
