Ward's path to the Spurs first team appears to be blocked
Ward spent the whole of last season on loan at the New York Stadium, scoring two goals and making another in 40 Championship appearances.

The 21-year-old has returned to Spurs in the meantime but was left out of the club's squad to tour Australia, despite a number of first team stars being unavailable.
And the likelihood is that Ward will be allowed to leave White Hart Lane, possibly on loan.
However, when questioned, new Rotherham boss Alan Stubbs refused to give too much away.
"I know he did very well here and I know he’s a good player. It would be wrong for me to elaborate on it any more," Stubbs told the Sheffield Star.

"But we are looking to bring in some talented players and he is a talented player. Whether it is him or any others, we’ll have to wait and see."
Right-winger Ward, who can also play in central midfield, signed a new contract with Tottenham in February, keeping him in north London until 2018.
And another year away from the club could be best for the youngster's development, with a number of players currently ahead of him at White Hart Lane.
Ward, who is a product of Spurs' academy, previously spent time on loan to Coventry City following a spell in Major League Soccer with Chicago Fire.
