Manchester United manager David Moyes has flown to Portugal to check on the form of three transfer targets. He is monitoring the Porto pair of centre-half Eliaquim Mangala, 23, Jackson Martinez, 27 - who plays as a striker - and Benfica left-back Guilherme Siqueira, 27, currently on loan from Granada.

Real Madrid are looking at Southampton's Luke Shaw, 18, and Benefica's Guilherme Siqueira, 27, as possible replacements for 26-year-old left-back Fabio Coentrao.

Liverpool defender Tiago Ilori, 20, is in talks over a loan move to La Liga side Granada. The centre-back has yet to feature for Brendan Rodgers's side following his £7m move from Sporting Lisbon in the summer.

La Liga side Granada are in negotiations with Rennes defender Dimitri Foulquier, 20, with a view to signing him on loan.

Liverpool could be set to fight neighbours Everton for 27-year-old left back Guilherme Siqueira, who may cost around £8m from Spanish side Granada.
