The late January loanee who can KO Manchester United's UCL dream

Paraguayan forward Nelson Valdez could be a dangerman Manchester United need to be aware of.

Manchester United defender Rio Ferdinand publicly thanked former coach Rene Meulensteen for signing Konstantinos Mitroglou from Olympiakos, meaning the Red Devils won't face the freescoring striker in their upcoming Champions League tie.

The Greek side did however make one late addition to their squad in an attempt to boost their firepower, who has been registered to feature in the clashes against United.

They signed 66-time capped Paraguayan international Nelson Valdez, a player who has played in the Bundesliga and La Liga for Borussia Dortmund and Valencia.

Valdez arrived on loan from Abu Dhabi based side Al-Jazira, for who he signed from Valencia for £2.6 million back in July.

Manchester United scouts were in attendance to watch him score his first goal for Olympiakos, coming off the bench at the weekend in the 4-2 win over Platanias.

Valdez is a striker who can play in the wide positions, and will certainly add the the Greek side's attacking options, despite the fact he has never been prolific during his career.

A superb header of the ball, he will be a danger to the Red Devils at set pieces and certainly give their centre-backs a battle.

At 30 he can count working under Jurgen Klopp on his CV, while scored his first ever La Liga goal against Barcelona, and won the Russian Cup with Rubin Kazan in 2012.

He has Champions League experience with 23 appearances in the competition, five goals and four assists, although won't remember coming up against a Michael Essien inspired Lyon well in 2005 with Werder Bremen, they were hammered 7-2.

Olympiakos coach Michel said at his signing: "He is a good player and we believe he can help us, he is strong with the ball at his feet and in the air. Olympiacos fans will love him."

It was Valdez' introduction at the weekend which helped turn the game in Olympiakos' favour, with the game at 1-1, he gave his side the lead after just 11 minutes on the pitch, coming off a substitute's bench which included former Manchester United goalkeeper Roy Carroll.

Young Nigerian forward Michael Olaitan has been prolific of late, hinting the side may not miss Mitroglou as much as feared, and Valdez' addition certainly gives the side an extra ounce of unpredictability heading into the tie with a Manchester United side they will be hopeful of pulling off a shock against.
