According to the Evening Standard, Callum Hudson-Odoi's representatives have requested the vacant No.10 shirt, supposedly as part of his new Chelsea deal.
And that could be a bit of an issue, as Willian also claimed in an interview that he was offered the No.10 shirt, and he obviously accepted it since he had used it throughout his career before arriving at Stamford Bridge.
While Frank Lampard confirmed that none of the new numbers are yet final, we can't have two players operating under the same assumption.
It should be noted that while the Evening Standard posits the shirt number as a contract issue, a deluge of recent reports already claimed that the new contract has been agreed.
The number of shirt Callum wears wasn’t enough to be a stumbling block in the negotiations. Let’s see who gets it— CarefreeYouth (@CarefreeYouth) July 25, 2019
Back in January, during the height of the Hudson-Odoi to Bayern Munich saga, it was reported that Callum had been offered the No.10 shirt as some sort of proof of his importance to Bayern. But his minutes at Chelsea ticked up regardless of what number he had been wearing anyway. His main concern has always been playing time rather than numbers of shirt, or indeed numbers on wage packets.
The No.10 shirt (usually) carries with it great symbolic significance and responsibility, and it is great that Hudson-Odoi is motivated enough to carry this weight at just 18. However, Willian has been a major part of Chelsea's trophy successes since 2013, so maybe he deserves a turn first.
Ultimately, there is no right or wrong choice, as long as everyone's happy.
And speaking of happy, here’s Callum getting back to it, whatever “it” may be.
