Baggies manager Roberto Di Matteo has confirmed his interest on signing the 19-year-old on a temporary basis but he could face competition from a number of other clubs. Italian side Sampdoria are confident of securing a deal.
Di Matteo was initially interested in acquiring the services of Macheda for a spell at the start of last season.
On the move? Manchester United striker Federico Macheda
There is much work to be done before any possible switch to the Hawthorns for Macheda goes ahead.
But Di Matteo admitted: 'Macheda is someone we looked at right at the start of last season. He's a striker, we are after a striker and we have to look at whether Manchester United will let him join us.'
Di Matteo has also been linked with Aston Villa's John Carew who has slipped down the pecking order.
Injuries to defenders Pablo Ibanez (hamstring) and Steven Reid (knee) during Saturday's 2-1 defeat against United mean Di Matteo is also considering adding in that department.
He said: 'We have to look at that possibility.'
Jonas Olsson is still sidelined with an Achilles injury while Gabriel Tamas is only one game into a three-match ban. But Gonzalo Jara will return after a one-game suspension for tomorrow's clash at Fulham.
