Lisandro Martinez has turned his frustration on Manchester United's leadership, publicly demanding more investment after a 2-0 defeat to Atletico Madrid left the club five games without a win.

The Argentine defender pulled no punches in his post-match assessment, arguing that a team which earned Champions League qualification by finishing third in the Premier League last season deserved to be properly backed in the transfer market.

"We did a fantastic season last season and now we expect more from the top, more players to compete because many teams bring many players as well. Atletico have an amazing team and they deserved to win today," Martinez said.

He went further, directly calling out technical director Jason Wilcox. "I expect more [investment]. 100%. I expect more from our technical director," he added.

Accountability across the board

While Martinez was pointed in his criticism of the club's hierarchy, he was equally honest about the players' own responsibilities. "I have to be honest, as players we have to do more but it is also important when you make a strong squad to be ready for this kind of night," he said.

The defender also pushed back against the instinct to pin the blame solely on the coaching staff or the playing squad. "Tonight it is easy to [blame] the coach, easy to say the players but also we have to see other areas," he warned.

A winless run that tells its own story

United's last victory came on 10 September, a Champions League group-stage win over Sabah FK of Azerbaijan. Their only other triumph this season was a come-from-behind league win over newly promoted Ipswich at Old Trafford — a slender record for a club with Champions League ambitions.

Manager Rubén Amorim and his squad now face growing pressure to turn results around, with Martinez's public broadside adding an internal dimension to the crisis at Old Trafford.
