Yann Sommer committed another game-defining mistake in Inter Milan’s heartbreaking 1-0 defeat to AC Milan last night.
According to Gazzetta dello Sport via FCInterNews, the 36-year-old was not the only underperforming Inter star.
Indeed, Hakan Calhanoglu endured one of his worst evenings in the Nerazzurri shirt.
Despite his outstanding start to the season, the 31-year-old midfielder faltered when the stakes were high.
In addition to missing his second penalty in Serie A, Calhanoglu lost the ball in the build-up to Milan’s second-half winner.
Yann Sommer Flops in Inter 0-1 AC Milan Loss

Yann Sommer couldn’t deal with Alexis Saelemaekers’ long-range shot.
Though the Belgian’s low effort looked destined for a bottom corner, Sommer had to do better.
Instead, his ‘soft’ deflection set Cristian Pulisic up perfectly, with the USMNT ace tapping the ball home from close range.
It’s also worth noting that Manuel Akanji lost sight of the Rossoneri talisman.
Akanji’s rare mistake heavily contributed to Milan’s sixth consecutive unbeaten match against the Nerazzurri.
However, Sommer could pay the price for Inter’s dismal derby loss.

I have been supporting inter for over 26yrs and I still find it hard to understand why the coach doesn’t want to use Martinez in goal, the guy has played well anytime he has been called into action and now we are hearing inter is interested in purchasing another goalkeeper to replace Sommer? We don’t have money but yet we can spend 15m on a promising goalkeeper and determine we are never going to give him a run of games. Because we believe more in experience, Italians need to change this attitude of always believing an older player is better than a younger player, it’s an outdated mindset that belongs to the Stone Age. Just look at premiership and la liga and German league and see the number of younger players in those leagues compare to Italian league. Febregas is changing a lot now playing younger players and everyone can see the result. All these are the reason why tv folks don’t want to invest the a Quater of the money they invest in Epl on serie a. It’s time to change
Çalha didn’t miss. He took the PK as he always does, but Milan has a GK who can really make difference.
