Manchester United are reportedly considering a summer move for Porto striker Jackson Martinez.
The Premier League outfit are believed to be in the market for a new centre-forward this summer, with Robin van Persie linked with a move away and Radamel Falcao's loan move from Monaco not expected to be made permanent.
According to the Daily Mail, United boss Louis van Gaal sent scouts to watch Martinez during Porto's 3-1 win over Bayern Munich in the first leg of their Champions League quarter-final.
Martinez scored his side's third of the match in Portugal, while the 28-year-old has netted 27 times in 36 games this season.
The Colombian international joined Porto from Chiapas in 2012.
