Manchester United could be ready to allow Alexander Buttner to leave the club this summer as speculation of another bid for Everton's Leighton Baines mounts.

The 24-year-old arrived at Old Trafford from Eredivisie club Vitesse Arnhem last summer as Sir Alex Ferguson sought cover for Patrice Evra, his first choice option on the left hand side of his defence.

Despite grabbing an assist and a goal for himself on his debut in a 4-0 win over Wigan Athletic, Buttner would make just three more starts in the league last season, in addition to a handful of appearances in domestic cup and low key Champions League outings.

Despite recent comments from Buttner suggesting he is ready to fight for his place, Dutch newspaper De Telegraaf reports that Turkish outfit Besiktas are monitoring the situation at Old Trafford and are prepared to make an offer for the defender with the promise of consistent first team football.

United are yet to make a significant transfer this summer but have seen a number of bids rejected, including one for Everton left back Leighton Baines in June.

But David Moyes remains determined to sign his former player as the Guardian suggest the Premier League champions are about to launch another effort to sign the England international along with his Toffees' team-mate Marouane Fellaini.

The potential arrival of Baines would almost certainly push Buttner further down the pecking order. With Evra, who has been United's first choice in the position for the past six years, and Fabio da Silva still in contention, the Dutch defender's opportunities could become even rarer during Moyes' first season at the helm.

When quizzed on reports of United's bid for Baines, Buttner said last month: "The speculation doesn't bother me. I hear the name Baines but for me I don't care.

"I want to play my own game. If he comes I don't think my future will be in danger. I just want to be strong and let the trainer see what I have got. I don't think about other players, just myself."

But with the 2014 World Cup now looming on the horizon, Buttner may feel his hopes of putting himself in the frame for a call up to Louis Van Gaal's Holland squad could rest on consistent first team football opportunities.
