Manchester United have revived their search for a left back creating further uncertainty over the long-term future of Patrice Evra.
The 31-year-old France defender, who has scored four times this season, has been in good form and there has been talk of a one-year extension to his contract which runs out in 2014.
However, United scouts watched Porto left back Alex Sandro in the recent Champions League tie against Malaga and plan to look at others in the position before the season ends.

United have reservations about the defensive capabilities of Evra and have studied several candidates to replace him. Everton's Leighton Baines has long been admired but his 15m valuation means an offer has yet to materialise.
United signed Alexander Buttner for 4m from Vitesse Arnhem in the summer but he has played just 10 games with only two in the Premier League.
Evra has been linked with Paris Saint-Germain, former club Monaco and Fiorentina but is eager to stay at Old Trafford.
Alex Sandro has six caps for Brazil and cost Porto 8m from Atletico Paranaense in 2011.
Declining: Despite a better season than last, Patrice Evra is not the player he once was
