His father is used to smashing records on a regular basis but now the newly arrived Thiago Messi has got in on the action – by becoming football’s youngest ever signing. Sort of.

Despite being unable to even focus his vision let alone kick a ball, the 7-day old son of the Barcelona genius has been snapped up by Argentine side Newell’s Old Boys.

The club, who Messi himself played for before securing a move to Barcelona as a 13-year-old, came to an agreement with Thiago’s grandfather Jorge to register him as their latest member.

The newborn-baby is now officially part of the club having been issued with a membership card and a shirt with the number 10 on the back – the same number Messi wears for Barcelona and the number he used while in his home country.

The Argentinian captain’s son will be presented with the items when club officials travel to Europe in the near future.

The late nights changing nappies since Thiago was born on November 2 appear to have taken their toll on Messi, who could do little to help Barcelona from succumbing to defeat against Celtic in the Champions League on Tuesday.

The 25-year-old found the net late on but couldn’t pull his side level, while he failed to score in his first game after becoming a father against Celta Vigo last weekend.

He appeared to have planned a celebration for the occasion by tucking a child’s dummy into his sock.

After the defeat at Celtic Park, Messi admitted his goal meant little to him, but said he hoped to score more in the future to dedicate to his son.

'My goal didn’t mean too much but I’m sure I’ll score many goals and significant victories to dedicate to the birth of my son,' he said.
