A picture has emerged showing Chelsea star Callum Hudson-Odoi as a starry-eyed schoolboy celebrating a goal with Samuel Eto'o.

The picture captures the South London-born player, now 18, celebrating with Eto'o after scoring a goal in a match against Manchester United in 2014.

Cameroon star Eto'o had just struck the final goal in his hat-trick in the 3-1 win over Manchester United and ran behind the net to greet the nearest ball-boy and the fans.

Hudson-Odoi is now a first-team star and England international after a stunning debut season in the Premier League and on the verge of signing a new £200,000-a-week deal.

Most footballers have humble beginnings and being a ball boy at the club you support, or even play for in the academy, is common amongst future stars.

However, football wouldn’t be anywhere near as fast-paced a sport without them.

As soon as the ball goes out of play, it’s their job to give either the same ball or a different ball back to one of the players as quickly as possible.

On the whole, they do an excellent job. However, there have been a few memorable examples of biased ball boys failing to give the opposition the ball quick enough because the home team is winning or has some other sort of advantage.

But these incidents are extremely rare. Ball boys and girls operate in every match and, by and large, there are virtually no problems.

Certain clubs will use players from their youth academies as ball boys on match days and some of these players have gone on to become famous footballers themselves and Callum Hudson Odoi name cannot be left out.
