When you sign for Liverpool, you best be aware of the club's history.
And that's a notion that new midfielder Alexis Mac Allister will be all too aware of after signing from Brighton for £45 million. The Argentinian star was given the choice of the No 10 or the No 8 jersey at Anfield, and opted for the former because of his past history with that shirt at other clubs.
It means that number so famously donned by Steven Gerrard for so long remains vacant. But in the meantime, the 24-year-old will now set about adding to the legacy of Liverpool No 10s, although not every Reds player to wear that number in the Premier League era has necessarily been a resounding success.
