Team GB's performance at this year's World Championships was somewhat underwhelming.Going into the event, it was expected that athletes from Britain will thrive from receiving the backing of a home crowd.That was the case in London 2012, when Team GB smashed their Olympic record total with ease; with athletes such as Greg Rutherford, Jessica Ennis-Hill, and Mo Farah spearheading a record breaking championships.But, five years on from that historic event, Britain's athletes failed to live up to expectations in the World Championships in London.There were some good performances, with Kyle Langford, Nethaneel Mitchell-Blake, and Dina Asher-Smith defying their age as they came so close to making the podium in their respective events.However, their near misses did not bring about any medals, and for large periods of the championships, team GB were well down in the standings.In fact, the opening eight days of the championships only brought about two medals; a gold and a silver won by none other than Mo Farah.Fortunately for Team GB, their championships were saved by their four relay teams, with each relay team winning a medal; most notably the men's 4x100m quartet who powered to gold with the third fastest time ever recorded in the event.But, on the whole, there was too many disappointing performances; as medal hopefuls such as Katarina Johnson-Thompson flattered to deceive. Therefore, there is reason for concern for the future of British athletics; an opinion that has been voiced by former 200m and 400m world record holder Michael Johnson.The American great, who won an incredible eight gold medals in the World Championships in an all-conquering career, shared his concern through a post on twitter.The post read: "GB performance at worlds: 4 thrilling relay medals. Only 1 individual medalist. Farah. He's retiring. £27m investment. I'd be concerned."

Although Johnson commended Britain's relay teams, he criticised the home nation's efforts as they only had one individual athlete to win a medal.

That, of course, was Mo Farah, who had already announced that this would be his last major championships in athletics.

Johnson also seemed to criticise the lack of medals in comparison to how much money had been provided for British athletics, with £27m investment only bringing a small return.

Although the American may have a point, it is not all doom and gloom for British athletics.

A number of fourth-placed athletes included Laura Muir, Dina Asher-Smith, Nethaneel Mitchell-Blake, and Kyle Langford; all of which are under the age of 24.

Despite her underwhelming performances, Katarina Johnson-Thompson is also only 24-years-old, meaning all of the athletes named above are still no where near their peak and will develop in the future.

So, although Team GB only had one individual medallist in London, a number of British athletes have shown that they have the potential to be on the podium in major athletics meets in the future.
