Roberto De Zerbi has insisted that he is neither angry nor frustrated with his Tottenham side despite their humiliating defeat to Brentford.Spurs suffered a shock 3-0 loss in their Premier League opener that has sent them to the bottom of the table.Spurs marked the start of their season with a poor performance at BrentfordGettyKeane Lewis-Potter, Vitaly Janelt and Michael Kayode all scored as the Bees beat their opponents at home for the first time since 1948.De Zerbi, who has begun his first full season in charge of Spurs, cast a dejected figure on the bench throughout the 90 minutes.What has De Zerbi said about Tottenham’s defeat?However, when speaking to talkSPORT after full-time, the Italian was not one to express any irritation with the result.When asked by Ian Abrahams if he felt angry or frustrated with his team, he simply said: “No, nothing.“Not frustrated or angry, I’m thinking a lot, what I can do to quickly improve the team.“In that way, I have my focus.”De Zerbi then added: “To become a team, maybe we need more time, to fight stronger, to be stronger in the duels.”What has been said about Spurs’ performance?Given it’s the opening weekend of the season and there is another 37 fixtures for Spurs to play, De Zerbi’s calmness may be unsurprising.However, talkSPORT host Rory Jennings was left stunned with Spurs and their display in west London.They had just four shots on target from a possible nine and only 18 touches inside the Brentford box.De Zerbi remained calm when reflecting on his side’s displayGettyJennings explained: “I’m not even talking in hyperbole here, when I think about Tottenham over the last 18 months.“The performance that we have just watched at Brentford is possibly the worst, or on par, with some of the dreadful performances I have seen from Tottenham under previous managers. What is going on?”Jennings continued: “De Zerbi had the back end of last season, he’s had a summer where I felt like Tottenham really got it right in the transfer market.“Look, I have no love for Tottenham whatsoever, but I was also conceding that I thought that (they) had a really good window.“I thought the signing of (Sandro) Tonali was a statement, I thought (Mateus) Fernandes under the nose of Manchester United was exactly what was needed.“Bringing in (Jan Paul) Van Hecke, elevating that backline, getting rid of (Cristian) Romero felt like a win,Brentford were levels above Spurs and deserved winnersGetty(Marcos) Senesi was intelligent, (Andy) Robertson was going to set the standards, but I just can’t believe it.”Jennings then stated: “This is as bad as a performance I can remember from Tottenham in recent memory, I think it genuinely is.”Four of Spurs’ six summer signings started in the defeat to Brentford, and more arrivals could be on their way.talkSPORT understands they are close to agreeing an £85million deal for Manchester City winger Savinho.Spurs are also in talks with City for Omar Marmoush as they look set to surpass the £350m mark this summer.They will be looking to return to winning ways against Charlton in the Carabao Cup second round on Wednesday night, before facing Newcastle next weekend.
