On 2 January 2014, former Manchester United striker Ole Gunnar Solskjær was hired as Mackay's replacement, but he was unable to save Cardiff from relegation. Solskjær left the club later that year and was replaced by Russell Slade.
In May 2014, the heaviest rains and floods in 120 years hit Bosnia and the surrounding region. The worst affected areas were the towns of Doboj and Maglaj, which were cut off from the rest of the country when all major roads flooded. Damage from landslides and floods was estimated to run into hundreds of millions of euros and twenty-four people were killed. The cost of the disaster, officials said, could exceed that of the Bosnian War. In June 2014, Tan made a personal donation of €114,000, while the people of Malaysia raised a total of €169,000 toward Bosnia's flood relief fund.
On 17 July 2014, during the halftime break of the Europa League qualifying match between FK Sarajevo and Norwegian club FK Haugesund at the Olympic Stadium in Sarajevo, Tan presented pledges of assistance of €255,000 each to two hospitals in Doboj and Maglaj, to be used for medical equipment. He said in a pre-match interview, "Because of my involvement with Sarajevo Football Club, when I heard about the floods, I urged the Sun newspaper to run a campaign to raise donations to help Bosnia."
In 2014, it was announced that Tan was part of a large ownership group involved with Major League Soccer club Los Angeles FC, who joined the league in 2018.
In April 2014, Tan (through one of his representatives) bought a two-year-old colt from Doncaster Bloodstock Breeze-Up Sales for £190,000. It will be trained by Australian Jeremy Gask in Wiltshire. Eamonn Wilmott, Gask's business partner, said: "We are very excited, and pleased to have Mr Tan involved. The horse looks exceptional and dominated the parade rings outside the sales."
