Manchester United are expected to make a deadline-day move for FC Porto striker Jackson Martinez.
Martinez scored 26 goals in 30 league games for the Portuguese outfit last season, catching the attention of several top European clubs in the process.
A Colombia international, Martinez is delaying on signing a new contract with Porto as he is believed to be keen on a move abroad.
United are understood to have been tracking Martinez for months, after club scouts targeted the prolific striker at the end of last season.
