Who is he? Where does he play?
As with all members of the Shakhtar Donetsk squad now, Costa is Brazilian, one of ten South Americans in fact who have traded sandy beaches and sunny climbs for the industrial lands of eastern Ukraine. The mining area of Donetsk is affluent , but the 22 year old midfielder is there to play football, winning 3 straight Ukrainian Premier League titles since his £6 million move from Gremio in 2010.
Is he any good?
Reported interest from Liverpool, Manchester City and Manchester United doesn't occur if you're rubbish does it? Part of the reckless abandoning Brazilian counter-attacking unit Mircea Lucescu has created at the Donbass Arena, Costa has been a consistent contributor as Donetsk have hoovered up domestic trophies making 120 appearances in 2 years whilst winning 6 trophies for the cutely named Kroty (The Moles).
Should he get a job on Blue Peter?
No, but he wouldn't look out of place creating things on there such is his creative talent behind the front-man. Equally at home on the wings, the skillful Brazilian likes to beat his man by cutting inside and threading balls in behind defences, making him integral to Lucescu's beloved 4-2-3-1. His style has drawn comparisons to Lionel Messi and Ronaldinho whilst his natural ability was never in doubt with his mother, bizarrely, claiming Costa even started playing football in the womb.
So why don't we see to much of him?
Being in the obscure reaches of mining-county Ukraine doesn't help, but if you were watching recent Champions League games with Chelsea et al. Costa was reduced to a bench role as Lucescu airs on the side of caution as he aims to negotiate a difficult group with Chelsea, Juventus et al. Previous links with Manchester United have died down but Sir Alex Ferguson remains a keen admirer, whilst Napoli have made their interest in the 22 year old attacker known.
