Massimo Cellino was reportedly watching two Barnsley players on Sunday.

The Whites chose to part company with Steve Evans on Tuesday, and Cellino is now looking for manager number seven of his time at Elland Road.

However, the Italian has also been scouting possible new signings, with a trip to Wembley on Sunday afternoon handing him the chance to watch two targets.
The Yorkshire Post report that chairman Cellino headed down to London in order to watch Barnsley beat Millwall in the League One play-off final, with defender Alfie Mawson and striker Sam Winnall the subjects of Cellino's interest.

Centre back Mawson, 22, had been on the books at Reading and Brentford, and after a series of loan spells, he moved on to Barnsley last summer.
With a host of impressive performances as Barnsley won promotion, Mawson has unsurprisingly attracted major interest, and with question marks over the future of Giuseppe Bellusci, Mawson could be an ideal solution to Leeds' defensive problems.

Meanwhile, striker Winnall, 25, was a target for former boss Evans in January, and hit 24 goals this term to help Barnsley win promotion, whilst he also scored 13 goals in the 2014/15 season, becoming one of the most dangerous strikers in League One.
With Chris Wood needing support in the final third, Winnall fits the bill - but whether Barnsley would be willing to sell to a Yorkshire rival in the same division remains to be seen, and Cellino may yet look elsewhere once a new manager is appointed.
