Midfield veteran Esteban Cambiasso produced a masterclass as Olympiakos stunned Arsenal at The Emirates.
The Argentine led the Greek Super League side to a 3-2 victory at The Emirates, demonstrating he is still capable of bossing games at the highest level.
That will come as no surprise to fans of Leicester City, who watched the midfield maestro inspire their side to an unlikely escape from relegation last season, momentum they have taken into this campaign.
The club attempted to persuade him to return for another year, but with the offer of Champions League on offer, the 35-year-old elected for a fresh challenge.
Former Real Madrid and Inter Milan midfielder Cambiasso completed 73 per cent of his passes at The Emirates, in a midfield alongside former Fulham ace Pajtim Kasami.
Cambiasso made five clearances and won two tackles, also making two interceptions, helping provide a platform for his side to pull off a shock result.
Leicester have started the season well but certainly could have done with their former star playing a similar role for them at the weekend, with Arsenal out-gunning them 5-2.
Here is a look at how Foxes fans reacted on Twitter to watching Cambiasso in action...
