Manchester United seem to have under achieved after such investments last summer, considering built-up expectations when Coach Jose Mourinho took over, but the club is not relenting.
The Premier League side is expected to spend huge sums this summer to restock.
There have been rumours that Real Madrid might come again for David De Gea. If this happens, United have reportedly placed Atletico Madrid keeper Jan Oblak on its shortlist.De Gea came close to leaving Old Trafford in 2015 but for a clerical error that stopped the deal from going through.
Though Mourinho would face intense competition for Oblak – who was rated the best keeper in the La Liga last season after he conceded just 18 goals –,there are rumours that the Slovenian is open to the move if the terms are right.
