Jose Mourinho has tipped Romelu Lukaku to continue improving after the striker scored his 100th Premier League goal in Manchester United's 2-0 home win over Swansea City.

The Belgium international netted the opener after five minutes at Old Trafford and Alexis Sanchez doubled the hosts' lead midway through the first half of Saturday's clash.

Lukaku has now scored 11 goals in his last nine games for club and country, and United boss Mourinho is optimistic about his player becoming even better as he accrues more experience and wisdom.

"His evolution is clear," the Portuguese told Sky Sports News. "At Chelsea he was obviously young but he got experiences at good clubs before he arrived at Manchester United and then mentally he is more than ready.

"Then it's details as a player; the movement, feelings, knowledge of every inch where he steps, which comes with experience, and at 24 there is a lot to learn and a World Cup to play this summer too, but the experience can only make him better."

Lukaku has made 45 appearances for United since his move from Everton last summer, scoring 26 goals and registering eight assists.
